Study of Factors Affecting Handoff Process in Wimax Network

WiMAX can make high speed wireless broadband internet services available to many larger areas. In Mobile WiMAX applications with speed up to 72 km/h; the handoff should take less than 50ms. In this study; the handoff latency, throughput and end-to-end delay, is measured and the parameters of the simulator are adjusted in order to achieve the best possible handoff times. The results of this study show that the handoff time could be reduced by adjusting link going down factor, scan iteration, scan duration, interleaving interval and timeout parameter. The handoff time is still below the 50 ms limit up to 28 m/s.
