Worldwide Interoperability for Microwave Access (WiMAX) specified by IEEE 802.16 supports Wireless Metropolitan Area Network (WMAN). In the environment of WMAN the mobile client has high mobility as it moves from the coverage area of Serving Base Station (SBS) to Target Base Station (TBS). Handoff is one of the Quality of Service (QoS) parameter in the WiMAX network which supports mobility and is the main challenging research in WiMAX network. The handoff is the process in which the mobile nodes switch from one BS to another until it gets the better signal quality. In this scheme Mobile Station (MS) scans for the TBS selection until it gets the better signal quality.
