Considerable attention is currently devoted worldwide toward mobility issues and challenges such as those arising from the integration of the next generation Internet over terrestrial digital TV, mobile user location management, and multi-service mobile networks subject to quality of service (QoS) routing. This book follows Heterogeneous Networks: Performance Modelling and Analysis. It describes recent advances in mobile and wireless networks and the Internet, reflecting the state-of-the-art technology and achievements in the study of mobility management, performance enhancement, optimal admission control, and QoS worldwide. Technical topics discussed in the book include - Mobility Management - Optimal Admission Control - Performance Modelling Studies - Access Network Coverage - Quality of Service (QoS) Mobility Management and Quality-of-Service for Heterogeneous Networks contains recently extended research papers, which have their roots in the series of the HET-NETs International Working Conferences. They focus on the 'Performance Modelling and Evaluation of Heterogeneous Networks' under the auspices of the EU Networks of Excellence Euro-NGI and Euro-FGI. This book is ideal for personnel in computer/communication industries as well as academic staff and master/research students in computer science, operational research, electrical engineering, and telecommunication systems.

Mobility Management in Wireless Networks available in PDF, EPUB and Kindle. In wireless communication systems, the network keeps track of a user’s location through an up-to-date user profile stored in various databases. A user profile contains not only a user’s current location information, but also service information, such as billing and authentication. The cov- age area of an access network is divided into registration areas (RAs), and each RA is associated with a location database. The two basic op- ations in mobility management are location update and location lookup. When a user moves across the boundaries of these RAs, the network updates his location information in the pertinent databases. When a caller places a call using the callee’s identification, the network queries the relevant database(s) to obtain the current location and other service information of the callee. The performance of mobility management can be further enhanced by using replicas of user profiles which may be kept at various locations. Replication techniques make profile information more readily available, thus reducing lookup cost and latency, but to keep these replicas c- sistent and fresh, they must be updated whenever the user profile is updated. The principle of replication is to replicate if the benefit of replication is greater than its overhead. The difficulty, however, lies in accurately measuring the benefit and overhead.

Interference and Resource Management in Heterogeneous Wireless Networks available in PDF, EPUB and Kindle. This authoritative resource offers a comprehensive overview of heterogeneous wireless networks, small cells, and device-to-device (D2D) communications. The book provides insight into network modeling and performance analysis of heterogeneous wireless networks. Interference management framework and design issues are covered as well as details about resource mobility, channel models, and typical and statistical interference modeling. This resource explains leveraging resource heterogeneity in interference mitigation and presents the challenges and feasible solutions for concurrent transmission. Moreover, complete coverage of interference alignment in MIMO heterogeneous networks for both downlink and uplink is presented. This book provides performance results for an ideal partially connected interference network as well as a practical heterogeneous network. Readers find practical guidance for LTE and LTE-Advanced as well as 5G in this resource. New techniques and designs for heterogeneous wireless networks are included.

The forthcoming fourth generation (4G) heterogeneous wireless networks are a mixture of overlapped networks using different wireless access technologies and addressing different needs from the users. Due to mobility, the users are able to switch connections among networks and hence to perform the so-called horizontal and vertical handoffs. The present thesis makes contributions to the field of mobility management with focus on handoff management and connection admission control in heterogeneous wireless networks. Two different integrated heterogeneous systems are investigated: 1) the interworking of cellular networks with wireless local area networks (WLANs) based on the I E E E 802.11 standard; 2) the interworking of cellular networks with wireless metropohtan area networks based on the I E E E 802.16e standard. To this end, first we develop a novel vertical handoff decision algorithm by modeling the vertical handoff problem as a Markov decision process. Our model considers the important tradeoff among the quality of service (QoS) of the connection and the signaling cost of performing a vertical handoff. We also take the connection duration into consideration for the handoff decision. Second, we propose an analytical model for admission control in c e l l u l a r / W L A N interworking and investigate the combination of different admission control policies. Our model considers mobihty of users, capacity and coverage of each network, admission policies, and QoS in terms of blocking and dropping probabilities. We introduce the concept of policy functions to model the admission control policies and formulate two different revenue maximization problems. T h i r d, we extend the virtual partitioning technique w i t h preemption for admission control in cellular/802.16e interworking. We propose admission control algorithms for each type of connection request. We also describe the expected mobility scenario in such integrated system. Finally, to achieve joint design at t.
