Abstract

A Mobile Station (MS)-controlled fast and simple scheme of handover (HO) in Mobile WiMAX network has been described. An MS can roughly estimate its present distance from any neighbouring Base Stations (BS) using the Received Signal Strength (RSS) and an appropriate pathloss formula. From the Mobile Neighbor Advertisement (MOB_NBR-ADV) broadcasts, the MS periodically monitors the RSS of its Serving BS (SBS), chooses the appropriate times to perform few scanning of selected Neighbouring BSs (NBS) and estimates their changing distances to compute their respective angles of divergence from its own line of motion. The MS selects the NBS having the minimum angle of divergence (AOD), coupled with satisfactory quality of service and bandwidth capability, as its Target BS (TBS) and requests the SBS for executing this HO. Simulation studies show fairly reduced HO latency. MS-controlled HO promises greatly increased scalability for the Mobile WiMAX network.
