Today it is hard to imagine our life without the use of such networks. Nevertheless, the development, implementation and operation of these networks require engineers and scientists to address a number of interrelated problems. Among them are the problem of choosing the proper geometric shape and dimensions of cells based on geographic location, fi nding the optimal location of cell base station, selection the scheme divid- ing the total net bandwidth between its cells, organization of the handover of a call between cells, information security and network reliability, and many others. This book mainly focuses on three types of problems from the above list - Positioning, Performance Analysis and Reliability. It contains four sections. The fi rst part is devoted to problems of Positioning and contains fi ve chapters. Here, the fi rst three chapters discuss various methods and models to solve these problems. Chapter 1 is a review devoted to a detailed analysis of the main problems regarding Positioning in wireless networks. Chapter 4 is devoted to a comparative analysis of the two most popular choices of the geometric structure of a cell - hexagon and circle. The fi nal chapter 5 of this part discusses some issues on signal processing using Smart Antennas. Part 2 contains eight Chapters which are devoted to quality of service (QoS) metrics analysis of wireless cellular networks. Chapter 6 is a review of known algorithms to calculate QoS metrics in wireless cellular networks with call admission control based on guard channels. Unifi ed approximate approach to QoS metrics calculations in multi-service wireless cellular networks under two multi-parametric call admission controls is proposed in Chapter 7. The proposed approach provides high accuracy. In Chapter 8, QoS metrics sensitivity to the fi rst three moments of both cell dwell time and unencumbered interruption time in cellular networks is investigated. In Chapter 9, authors propose two channel assignment schemes in multihop cellular networks - asymmetric fi xed channel assignment and multihop dynamic channel assignment. For both schemes exact and an approximated multi-dimensional Markov chain models are developed to analyze its QoS metrics. In Chapter 10, call admission control and adapta- tion (degradation and improvement) issues for elastic calls under restricted resources and bandwidth fl uctuation has been considered. In Chapter 11, joint call admission controls algorithms in heterogeneous cellular networks are developed and their per- formance is investigated through numerical simulations. In Chapter 12, three call admission control strategies (i.e. resource reservation, queuing, and preemption) in public cellular networks with emergency services is proposed. Novel analytical mod- els to evaluate the performance of seamless handover in mobile IPv6-based cellular networks are developed in Chapter 13. X Preface Part 3 contains two Chapters and these Chapters deal with reliability issues of wireless cellular networks. In Chapter 14 Bayesian network model and mobile intelligent agents approaches are combined for automating fault prediction in wireless cellular networks. In Chapter 15, the application of forward error correction in Multimedia Broadcast over Single Frequency Network transmissions over long term evolution wireless cellular networks is examined. Last Part 4 is a special one and it contains only one Chapter 16 in which basic mecha- nisms of the metabolic network coordination are proposed and their applications in both primary and complex networks are shown. The book will be useful to researches in academia and industry and also to post-gradute students in telecommunication specialitiies.
