RESOURCE MANAGEMENT SCHEMES IN WIRELESS AND MOBILE NETWORKS
Abstract (Summary)A rapid increase in the size of the wireless mobile community and its demands for high-speed multimedia communications have been subjected to rather limited spectrum resource that have been allocated as per international agreements. Efficient radio resource management is of paramount importance due to these increasing demands. Good resource management schemes should support as many as possible mobile users while maintaining the necessary QoS. First, the notions of QoS for wireless and mobile networks are very different from fixed networks due to the restrictions and limitations of the air interface. Moreover, the next generation wireless and mobile networks have been designed to support true convergence of multi-class services that have distinct characteristics and performance requirements. In this dissertation, several efficient resource allocation schemes have been developed to improve the system performance, including the near optimal channel partitioning scheme, priority cutoff scheme, adaptive channel allocation scheme and power-based call admission scheme for CDMA system. A comprehensive set of QoS metrics is also defined and analytical models are carried out to derive the closed form expressions of these QoS parameters and to investigate the impact of resource management schemes on the system performance. Extensive simulation results show that the proposed schemes outperform existing resource allocation schemes under various scenarios. Furthermore, not only schemes for resource management in integrated wireless and mobile networks are provided in this dissertation, but also solutions for future generation wireless and mobile networks. Finally, we conclude this dissertation with some promising future work in the area of future generation wireless and mobile networks.
