ABSTRACT
Th is chapter presents a comprehensive set of radio resource management algorithms for the Mobile WiMAX network, including call admission control, adaptive transmission, horizontal handover, and vertical handover algorithms. Th ese algorithms are based on our system load model of the Mobile WiMAX network. Each algorithm individually and all algorithms as a whole satisfy Quality-of-Service (QoS) requirements and maximize the network capacity. Th e sections of this chapter are divided into two groups, that is, the basic ones and the extensions. In the basic sections, we give a brief overview of the Mobile WiMAX system, describe our system load model of the Mobile WiMAX network, present call admission control, dynamic bandwidth allocation, adaptive transmission, and horizontal handover algorithms, and show how all radio resource management algorithms operate together. Th e fi rst extension is devoted to the QoS-guaranteed load-balancing vertical handover
algorithm in the 4G heterogeneous wireless network. In the second extension, which is the last section, we describe our vision of the future research on improvement of the Mobile WiMAX network.
