Book Description
The study of the channel allocation problem has received much attention during the last decade. Several techniques such as genetic algorithm, artificial neural network, simulated annealing, tabu search and others have been used. This book is devoted to compiling all the techniques that have been used to solve the channel allocation problem. Each of the methods is described fully in a manner that explains the essential parts of how the techniques are formulated and applied in solving the problem. This textbook will be helpful to students studying communications or researchers as it compiles all the techniques used since this problem was first solved.

Book Description
Efficient allocation of radio spectrum becomes increasingly important as the demand for wireless communication has been growing rapidly over the past two decades. Several channel assignment algorithms for increasing channel utilization have been studied. In Fixed Channel Assignment (FCA), channels are permanently allocated to each cell for its exclusive use, whereas in Dynamic Channel Assignment (DCA) the channels are put in a shared pool and dynamically assigned upon request. One example of a DCA scheme is the so-called greedy strategy, where all the channels are kept in a central ordered list and every node uses the first channels which are available. In Fixed Preference Assignment (FPA), each cell has a fixed preference list of all channels and the first available channel in the list will be used to serve an incoming call. In this thesis, we show upper bounds and lower bounds for the competitive ratios of the greedy and FPA strategies for different values of reuse distance. The average case performance analysis of these three schemes is also conducted using computer simulation.

Book Description
Channel assignment in multi-radio networks is a topic of great importance because the use of multiple channels and multiple radios reduces interference and increases the network throughput. The goal of our research is to design algorithms that maximize the use of available resources while providing robustness to primary users that could reclaim one or more channels. Our algorithms could be used in ad hoc networks, mesh networks, and sensor networks where nodes are equipped with multiple radios. We design algorithms for channel assignment which provide robustness to primary users without assuming an accurate primary user behavior model. We also compute bounds for capacity in grid networks and discuss how the capacity of a network changes when multiple channels are available. Since preserving energy is very important in wireless networks, we focus on algorithms that do not require powerful resources and which use a reduced number of messages.

Book Description
Cognitive radio technology that enables dynamic spectrum access has been a promising solution for the spectrum scarcity problem. Cognitive radio networks enable the communication on both licensed and unlicensed channels, having the potential to better solve the interference and collision issues. Channel assignment is of great importance in cognitive radio networks. When operating on licensed channels, the objective is to exploit spectrum holes through cognitive communication, giving priority to the primary users. In this dissertation, we focus on the development of efficient channel assignment algorithms and protocols to improve network performance for cognitive radio wireless networks. The first contribution is on channel assignment for cognitive radio wireless sensor networks aiming to provide robust topology control, as well as to increase network throughput and data delivery rate. The approach is then extended to specific cognitive radio network applications achieving improved performances.
