Mobility Management Issues in Heterogeneous Mobile Wireless Networks
Leo Bhebhe (Nokia Siemens Networks, Finland)
Future wireless network will have a mix of different radio access technologies co-existing. Individual wireless access networks show limitations and by having them co-exist operators have tried to minimize the limitations. However, the integration of heterogeneous networks poses many challenges such as adding complexity to the processes of selecting the optimal radio access technology, seamless vertical handover between heterogeneous technologies and adaptation of multimedia transmission between heterogeneous technologies. This paper aims to provide an insight into these mobility management issues in heterogeneous networks, present proposed solutions and their drawbacks, and focuses on the enhancements required to provide a better quality of user experience.
A new algorithm of virtual network embedding based on minimum node stress and adjacent principle
Hongyan Cui (Beijing University of Posts and Telecommunications, Wireless Technology Innovation Labs, P.R. China); Fangjie Kong (Beijing University of Posts and Telecommunications, P.R. China); Yunjie Liu (Beijing University of Posts and Telecommunications, P.R. China)
As the main approach of solving the ossification of current internet, network virtualization has been the focus of international future network research. The core problem of the area is virtual network embedding, which is centering on how to efficiently map the virtual requests to the substrate network. In order to reduce the computational complexity, previous researches mainly devise heuristic algorithm and divide the whole process into node mapping and link mapping. But most of them consider separately node mapping and link mapping, which may lead to poor performance of the whole algorithm because of the unreasonable node mapping. In this paper, a new algorithm is proposed based on the minimum node stress and adjacent principle. During the period of node mapping, the node stress is kept balanced. Meanwhile, using the adjacent principle, the link stress can be reduced to a low level. Thus, the possibility of bottleneck node is reduced and the resource of substrate network can be efficiently used. The simulation demonstrates that the new algorithm reduces the maximum node stress and link stress of the substrate network, and makes it load balance.
An Adaptive Source Rate Regulation Scheme for Wireless Periodical Data Collection Systems
Yusuke Matsuda (Niigata University, Japan); Kenichi Mase (Niigata University, Japan)
It is often useful and necessary to periodically collect data from many geographically distributed data sources such as sensors and smart meters in applications such as environmental monitoring and smart community applications. In periodic data collection, each data source performs data acquisition every constant period and sends the data to the corresponding data sink as quickly as possible. When multiple data sources periodically send the data to the data sink, interference and collision may occur on the wireless channel, causing severe data loss and transmission delay as well as excessive energy consumption. In this paper, we focus on source rate regulation together with data acquisition time (sampling time) coordination among sources such as synchronous and asynchronous samplings in periodic single hop data collection. It was shown based on simulation that asynchronous sampling works well without changing the basic CSMA/CA parameters and keeps the near optimum throughput by dynamically adjusting the source rate.

Future Internet will constitute a complex and dynamic environment, the requirements of which cannot be handled by traditional management schemes. The alternative is the approach of autonomic service and network management, which targets at guidance and orchestration of the behavior of autonomic and legal network entities based on specific service requirements and business goals. In this context, policies can constitute a means for accomplishing the desired high level control in autonomic management. In order to achieve this objective, an advanced policy framework confronting the challenges of the highly miscellaneous, decentralized and dynamic Future Internet. To this effect, this paper presents the main challenges of policy-based management in the context of governing the autonomic Future Internet, and based on their elaboration, the focus is placed on existing concepts that can constitute the basis for the design of a proper policy management framework. The paper also describes the functional specification of the policy management, deriving from the presented challenges, and instantiation of the policy framework on an indicative scenario.
Auto-Collaboration for Optimal Network Resource Utilization in Fixed IPv6 Networks

Autonomic Networking is seen as one of the hopes to improve the Quality of Service (QoS) provided to end users in the Internet. Especially in the context of Video on Demand (VOD), content and network providers have to deal with the dynamics of network and server loads which can severely impair the services provided to end users. Our recent research efforts seek to provide a remedy for this issue by introducing an autonomic framework for optimal network resource utilization that allows content and network providers to cooperate, and take into account aspects of the network state as well as server loads while optimizing the services for their subscribers. The framework is specified, designed, and implemented in an IPv6 testbed that was setup by the participating partners in the course of a large scale European project. Finally, a scenario realized in this testbed is presented that illustrates the benefits of the proposed approach.
Performance Evaluation of LTE EPC Self- Healing Solutions
Md. Mustafizur Rahman (University of Ontario Institute of Technology, Canada); Shahram Shah Heydari (University of Ontario Institute of Technology, Canada)
The Long Term Evolution (LTE) defined by 3rd Generation Partnership Project (3GPP) is a dominant cellular wireless technology which is currently being commercialized worldwide. In this paper we evaluate the performance of self-healing schemes for LTE Evolved Packet Core (EPC) network elements failures in different architectural configurations. We also analyze message overheads and bandwidth requirements for signaling traffic incurs by this design and its ramification to LTE core network. The simulation experiments are conducted to evaluate the performance of the self-healing schemes.

China); Xirong Que (Institute of Networking Technology, P.R. China); Gong Xiangyang (Beijing University of Posts and Telecommunications P.R. China, P.R. China)
Software Defined Networking (SDN) is a new area in network management. It is understood as using software to improve the network capabilities and intelligence. Autonomicity is one of proposed technologies, which also can improves network management capabilities. A scheme of the combination of Openflow based SDN and Autonomicity is proposed in this paper to introduce self-* attributes into Openflow Based SDN so that the network could be better controlled and operated efficiently.

Construction and Evaluation of a Regional Protection System Employing Power-saving Wireless Terminals without Using GPS Modules
Hiroaki Nose (Nagano Prefectural Institute of Technology, Japan); Hideki Motoyama (Nagano Japan Radio Co., Ltd., Japan); Hikofumi Suzuki (Shinshu University, Japan); Yasushi Fuwa (Shinshu University, Japan)
In recent years, there have been many cases of violent crimes against children. As a result there is an increasing need for systems which can identify the current positions of children, and keep watch over them in time slots where they may be alone, such as on the way to and from school. At present, the most typical approach is to have the children carry a wireless terminal so they can be tracked, but the power-saving performance of such devices needs to be improved. As a result, we have proposed a method of estimating the position of children without using GPS, and thereby improved the power-saving performance of the wireless terminals. In addition, we have confirmed through measurement experiments in an experiment field that the position of children can be appropriately estimated using this technique.
Multiplatform Management of a Hard Real-Time Ethernet Switch
Aleksander Pleszko (University of Aveiro, Portugal); JoŃo Paulo Barraca (University of Aveiro & Instituto de Telecomunicaš§es, Portugal); Joaquim Ferreira(University of Aveiro, Portugal); Pedro A. Gonšalves (Universidade de Aveiro, Portugal)
The Hard Real-Time Ethernet Switch (HaRTES) allows using the same network to handle multiple traffic flows, without compromising the performance of real-time applications. Furthermore, it also provides flexible and on-line scheduling techniques with admission control capabilities, thus real-time communications flows can be added, removed and updated online with strict temporal isolation. However, HaRTES lacked a standard management interface to configure its parameters and view its status. This paper describes a multiprotocol (SNMP and NETCONF) management interface design, and implementation. It also presents a preliminary validation of the two management technologies.

As a long term solution to the gradual ossification problem faced by the existing Internet, virtual networks can guarantee on-demand requirements of diversity end user on a global level. Clearly it is a major challenge to achieve the automation and optimization of network management like resource or QoS to ensure the personalized user satisfaction. In this article, we propose a novel cognitive management architecture to meet the future needs under the heterogeneous network environment. The architecture introduce the cognitive cycle to the virtual network resources to ensure flexibility. We also focus on the efficient virtual network resource allocation and scheduling algorithms. Based on the complex network centrality analysis, we solve the virtual network resources allocation problem with consideration of the topology structure and statistical analysis. Finally we evaluate the efficiency and effective of our algorithm on the common benchmarks including the acceptance, revenue and cost.

Link Sleeping Optimization for Green Virtual Network Infrastructures
Ebrahim Ghazisaeedi (University of Surrey, United Kingdom); Ning Wang (University of Surrey, United Kingdom); Rahim Tafazolli (University of Surrey, United Kingdom)
Power consumption in Information and Communication Technology (ICT) is 10% of total energy consumed in industrial countries. According to the latest measurements, this amount is increasing rapidly in recent years. In the literature, a variety of new schemes have been proposed to save energy in operational communication networks. In this paper, we propose a novel optimization algorithm for network virtualization environment, by sleeping reconfiguration on the maximum number of physical links during off-peak hours, while still guaranteeing the connectivity and off-peak bandwidth availability for supporting parallel virtual networks over the top. Simulation results based on the G╔ANT network topology show our novel algorithm is able to put notable number of physical links to sleep during off-peak hours while still satisfying the bandwidth demands requested by ongoing traffic sessions in the virtual networks.

Preventive Network Protection in Probabilistic Large-Scale Failure Scenarios
Alireza Izaddoost (University of Ontario Institute of Technology, Canada); Shahram Shah Heydari (University of Ontario Institute of Technology, Canada)
Large-scale failure resulting from natural disasters or intentional attacks is now considered a serious risk for communication network infrastructure. The impact of large scale network connection disruptions may cause significant costs for service providers and subscribers. In this paper, we develop a novel approach for preventive protection of the network based on a probabilistic model for large-scale failure scenarios. In particular, we aim to develop a scheme to improve uninterrupted delivery of data in the network to provide desired services in case of large-scale failures. We conduct simulations to show the significant reduction in the average number of disrupted connections and network disruption time due to failure.

Column Generation Approach for One-Shot Virtual Network Embedding
Abdallah Jarray (University of Ottawa, Canada); Ahmed Karmouch (University of Ottawa, Canada)
Network Virtualization has been proposed as new promising resource management approach that allows multiple customized Virtual Networks (VNs) to be setup on a shared physical infrastructure. In this paper, our focus is on the embedding problem which consists on the mapping of VN resources onto physical infrastructure network. Since this problem is known to be NP-hard, in literature, number of approaches have been proposed heuristic based-embedding algorithms. The mapping of VN links and nodes are performed on two separate stages, which may ensue in a high blocking of VN requests and an under-utilization of substrate resources. To handle these drawbacks, we propose a mathematical model which makes use of large scale optimization tools and propose a Column Generation formulation coupled with a Branch and Bound technique in order to solve it efficiently.
Multi-Granular Optical Transport Network Design with Dual Power State
Nabil A Naas (University of Ottawa & Tripoli University, Tripoli-Libya, Canada); Burak Kantarci (University of Ottawa & School of Electrical Engineering and Computer Science, Canada); Hussein T Mouftah (University of Ottawa, Canada)
Bandwidth utilization and management advancements of Multi-Granular Optical Transport Networks (MG-OTN) have been shown to couple with power savings through lowered port counts. In this paper, we propose energy-efficient design of MG-OTNs by adopting multiple power levels at the MG nodes. Our proposed scheme combines the advantages of a previously proposed energy-efficient design method and introducing dual power state behavior to the MG nodes. According to the proposed scheme, a node can be either in the on state where it can add, drop and forward traffic at any granularity, or in the sleep state where it can only add and drop traffic, and accordingly, it saves the switching power consumption due to pass-through traffic. Through extensive simulations, we evaluate the proposed dual power state-based MG-OTN design in terms of energy-efficiency. Numerical results confirm that for all tested traffic patterns, putting a certain number of nodes in the sleep mode can guarantee significant power savings. Furthermore, we provide information on optimal selection of the nodes that have to be put in the sleep mode. Moreover, we study the topology dependence of the proposed scheme and show that high network connectivity leads to high power savings.
Network Construction Management for Emergency Communication System SKYMESH in Large Scale Disaster
Hiraku Okada (Nagoya University, Japan); Hironori Oka (Niigata University, Japan); Kenichi Mase (Niigata University, Japan)
As an emergency communication system for the large scale disaster, a wireless network using balloons, SKYMESH, was proposed. In this paper, a network construction method for SKYMESH is proposed. At first, network construction requirements for SKYMESH are clarified. Based on these requirements, we discuss node placement procedure and the network construction method. The proposed network construction method is implemented, and its performance is evaluated by experiments. As a result, the network can be constructed by the proposed method within allowable elapsed time. In addition, interference between links can be suppressed, and high throughput can be achieved in the constructed network.
Throughput Enhancement for VHT WLANs Based on Two Level Network Allocation Vector
Baofeng Ji (Southeast University, P.R. China); Kang Song (Southeast University, P.R. China); Chunguo Li (Southeast University, P.R. China); Yongming Huang (Southeast University, P.R. China); Yang Luxi (SouthEast University, P.R. China)
Recently, very high throughput (VHT) WLANs have attracted extensive attentions for achieving transmission rates over 1 GHz for the 5GHz band and support the MU-MIMO transmission mechanism and maximum 160MHz bandwidth, which makes the carrier sensing mechanism emerge some drawbacks especially when there is not only one BSS. The paper proposes TLNAV (Two Level Network Allocation Vector) scheme and some frame structure modifications are also provided under the current standard and gives the performance analysis of the scheme proposed. The probability density functions of the throughput gains in SU/MU mode are calculated in closed form, then we obtain the expectation of the throughput gains, and the analysis of schemes proposed are analyzed and verified through simulations. The results show that the scheme proposed can obtain bigger performance gains than the current scheme.
Fuzzy Non-dominance multipath link-state routing framework for network routing management with inaccurate information
Jing An (King's College London, United Kingdom); Paul Pangalos (Kings College London, United Kingdom); Hamid Aghvami (King's College London, United Kingdom)
An open problem for quality of service routing management is the use of inaccurate metric information. Due to periodic link-state update, the router always remains out-of-date information in a dynamic network. This paper proposes a novel framework for routing management with inaccurate information. We introduce a fuzzy metrics representation and the concept of non-dominance or Pareto-optimal fuzzy shortest path routing into our framework. The term fuzzy shortest path routing used here is distinct from the classic sense of fuzzy rule controlled routing. We map the crisp link-state information to a new plane by fuzzification factor, and use fuzzy non-dominated multipath routing algorithm for path selection in order to achieve a better network usage. Under our framework, it is easy for network administrator switch between fuzzy or non-fuzzy routing. We will discuss and investigate how this framework could be merged with the current network infrastructure to support better QoS for emerging services and applications. A case study is shown in the paper, and simulation result is also included to validate network preference enhancement under our framework.

Rotary Dial Model - A Model-Driven Methodology for Autonomic Network Design
Arun Prakash (Fraunhofer FOKUS & Technische Universitńt Berlin, Germany); Ina K Schieferdecker (TU Berlin/Fraunhofer FOKUS, Germany); Michael Wagner (Fraunhofer FOKUS, Germany); Christian Hein (Fraunhofer Fokus, Germany)
Designing and developing autonomic systems and networks is not only a creative but also a systems engineering challenge. Current systems engineering methodologies are unsuitable, as autonomics is a multi-domain field that requires the knowledge of several domains and comes with its own set of requirements and challenges. We showcase why and how current systems engineering approaches fail, and advocate for an avant-garde systems engineering approach to designing autonomic entities. In this paper, we introduce a new model-driven systems engineering methodology, called the Rotary Dial Model (RDM), whose functioning is inspired from the standard telephone rotary dial. We describe in detail the working of the RDM model, and showcase its robustness and flexibility for the system design process.
The Self-Growing Concept as a Design Principle of Cognitive Self-Organization

Koudouridis (Huawei Technologies Sweden R&D Center & Royal Institute of Technology, Sweden)
In next generation systems and networks self- organization in networks of collaborating networks is expected to relax some of the intricacies of managing complex cooperative communication systems. In particular, in the presence of distributed cognitive decision-making, increasing complexity may increase potential interference between collaborating networks hence leading to performance, robustness and dependability issues. This paper focuses on a specific form of self-organization denoted here as self-growing, which is believed to provide a foundation for flexible, open and trustworthy networks, relax some of the scalability issues of collaborating cognitive networks, as well as to enable self- organization for resource constrained systems..
Testbed Implementation for Autonomic Network Performance Management of Wireless Mesh Networks
Abdelhamid G Moursy (University of Louisiana at Lafayette, USA); Ahmed Aly (University of Louisiana at Lafayette, USA); Bide Xu (University of Louisiana at Lafayette, USA); Dmitri Perkins (University of Louisiana at Lafayette, USA); Magdy Bayoumi (University of Louisiana, USA)
In previous work, we proposed an Autonomic Network Performance Management (ANPM) framework that follows a control-theoretic approach. We built and verified the framework using network simulations but there were many questions needed to be accurately answered concerning the feasibility of such framework in real networks. In this paper, we are going from simulation to testbed implementation to accurately answer such key questions. We used over-the-counter platforms and open source software to build the test-bed that supports 700 MHz, 2.4 GHz, and 5 GHz frequency bands. Multithreaded code is written to automate the process of ANPM.
Autonomic Cooperative Networking for Emergency Communications
Michal Wodczak (Ericsson, Poland)
A modern emergency network formed by First Responders is characterised by the need for urgent provision of a seamless, durable and uninterrupted information exchange in the area of incident. Such a requirement may by addressed by the incorporation of both the concept of cooperative communications and the rationale of autonomic system design. In particular, the cooperating Relay Nodes may be instantiated by Chief First Responders equipped with terminals capable of forming Virtual Antenna Arrays, while the whole system is expected to self-configure on the spot. This paper discusses these aspects jointly by investigating the mapping of autonomic cooperative
communications onto an emergency network formed in an indoor scenario.

GARSON is a new approach to autonomic and cognitive network management. In this paper the main GARSON features together with short background explaining its position among other research projects are described. GARSON consists of several 'planes' playing different roles in the network management hierarchy. Main planes are described in more detail, especially the autonomic monitoring plane and autonomic actuating plane. The basic structure of GARSON network components is given as well. The conclusions are derived at the end of this paper, showing the possible usage areas of GARSON concept.
A Game Theory Approach: Dynamic Behaviours for Spectrum Management in Cognitive Radio Network
Saed Alrabaee (Concordia University, Canada); Mahmoud Khasawneh (Concordia University, Canada); Anjali Agarwal (Concordia University, Canada); Nishith Goel (Cistel, Canada); Marzia Zaman (Cistel Technology Inc., Canada)
We are considering the problem of the dynamic behavior for spectrum management in cognitive radio networking. The spectrum management, which consists of spectrum trading and spectrum competition, is considered with multiple spectrum owners (primary users) and spectrum leaser (secondary users). The primary users compete with other primary users in order to get more spectrum leasers. As a result, the primary users can adjust their behaviors in renting the spectrum to secondary users in order to achieve higher profits. The secondary users can adjust the spectrum renting by observing the changes in the price and the quality of the spectrum. It is problematic however, when the decisions made by primary users and secondary users are made dynamically. To address this problem, a three layer game theoretic approach is introduced in this paper. The upper layer models the spectrum competition among primary users; a Bertrand game is formulated; where the Nash equilibrium is considered as the solution. The middle layer models the spectrum trading between the primary user and secondary user; a Stackelberg game is formulated, where the Nash equilibrium is considered as the solution. The lower layer models the dynamic selection strategies among secondary users in order to select the offered spectrum with the QoS level; an evolutionary game is formulated, where the Nash equilibrium is the solution. Basically, the solution in each game is found in terms of the size of the offered spectrum to the secondary users and the spectrum price. The proposed game theory model is used to examine network dynamics under different levels of QoS. Three levels of QoS are introduced as well.
