Book Description
This book focuses on the current hottest issues from the lowest layers to the upper layers of wireless communication networks and provides "real-time" research progress on these issues. The authors have made every effort to systematically organize the information on these topics to make it easily accessible to readers of any level. This book also maintains the balance between current research results and their theoretical support. In this book, a variety of novel techniques in wireless communications and networks are investigated. The authors attempt to present these topics in detail. Insightful and reader-friendly descriptions are presented to nourish readers of any level, from practicing and knowledgeable communication engineers to beginning or professional researchers. All interested readers can easily find noteworthy materials in much greater detail than in previous publications and in the references cited in these chapters.

Book Description
Call Admission Control (CAC) and Dynamic Channel Assignments (DCA) are important decision-making problems in mobile cellular communication systems. Current research in mobile communication considers them as two independent problems, although the former greatly depends on the resulting free channels obtained as the outcome of the latter. This book provides a solution to the CAC problem, considering DCA as an integral part of decision-making for call admission. Further, current technical resources ignore movement issues of mobile stations and fluctuation in network load (incoming calls) in the control strategy used for call admission. In addition, the present techniques on call admission offers solution globally for the entire network, instead of considering the cells independently. CAC here has been formulated by two alternative approaches. The first approach aimed at handling the uncertainty in the CAC problem by employing fuzzy comparators. The second approach is concerned with formulation of CAC as an optimization problem to minimize call drop, satisfying a set of constraints on feasibility and availability of channels, hotness of cells, and velocity and angular displacement of mobile stations. Evolutionary techniques, including Genetic Algorithm and Biogeography Based Optimization, have been employed to solve the optimization problems. The proposed approaches outperform traditional methods with respect to grade and quality of services.

Book Description
Efficiency in managing scarce wireless resources has been a major design obstacle in wireless mobile networks since its advent. A large body of work has been published on the subject in relation to the first two generation and third generation (3G) of wireless networks. However, these solutions are not readily applicable to the future IP based multi-hop wireless networks. Increased trend in the number of users accessing multimedia rich traffic, and the impacts of mobility management support mechanisms alongside the shared nature of backhaul nodes demand exploration of new avenues of resource management policies. In this thesis a set of schemes are proposed to address the issue of Call Admission Control (CAC) in future multi-hop IP based mobile networks. The first scheme is based on a joint CAC and route assignment design mechanism in Wireless Mesh Networks (WMNs) environment, addressing issues such as pricing policies, wireless resource constraints of the access and backhaul links as well as maximising network provider's revenue. Study's focus is then shifted towards CAC design in Mobility Agent (MA) based Proxy Mobile IPv6 (PMIPv6) networks. A novel class-based CAC mechanism was proposed with the aim of eliminating bottleneck effect at the MAs. To further improve the overall capacity of the network, in conjunction with the proposed CAC mechanism, a modified version of a previously proposed Route Optimisation (RO) scheme is implemented. The performance of the proposed schemes is investigated and analysed through extensive simulations. Comparative studies are then carried out to examine the network provider's total revenue gain in WMNs environment, total blocking probability and per class blocking probability in PMIPv6 networks.
