Efficient clustering mechanism for WiMAX network

WiMAX is a technology based on IEEE 802.16 standard that enables the delivery of last mile wireless broadband access as an alternative to wired access such as cable or DSL. WiMAX can provide mobile wireless broadband connectivity without the requirement for direct line-of-sight with a base station. With the development of wireless network, WiMAX has the characteristics of long transmission distance, wide coverage, high speed, multiple bands, and support of multi-media. In an environment with large population, the network may become unstable and broadcast storms because of interferences from excessive communications when too many users are using their mobile devices for communications. A Three-Layer based WiMAX network topology (TLWiMAX) is proposed to address the scalability of WiMAX in order to reduce packet collisions and rapid energy consumptions by excessive broadcasting. By doing so, the lifecycle of the device can be extended and the network made more stable.
