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.
