Abstract

The Mobile WiMax system is a promising solution for delivering broadband wireless access services to mobile users. Radio resource management (RRM) algorithms play a key role in the Mobile WiMax network. The Mobile WiMax network has a number of distinct features that complicate the use of conventional RRM algorithms. We propose load-balancing approach to RRM in the Mobile WiMax network. To illustrate the advantages of the load-balancing approach, we present RRM algorithms, including call admission control, adaptive transmission, horizontal handover, and dynamic bandwidth allocation algorithms. These algorithms jointly maximize the network capacity and guarantee users quality-of-service requirements.
