Different aspects of wireless networks are changing as a result of the continuous needs in terms of speed, data rates and quality of service. Such aspects are required to be adaptable within the same network or among networks of different technologies and service providers. Consequently, Worldwide interoperability for Microwave Access (WiMAX) is one of the Fourth Generation networks (4G) that needs further study. However, a major consideration for WiMAX to achieve mobility is the handover mechanism that concerns with the mobile station movement within the range of network coverage from one base station to another similar homogeneous or different homogeneous network.
