An enhanced handover target cell selection algorithm for WiMAX network

Abstract

WiMAX is one of the most promising technologies which is to go through wireless broadband last mile access. Handover procedure plays a crucial role in the mobile WiMAX application. This paper introduces an implementable enhanced handover target cell selection algorithm for WiMAX network based on the effective capacity estimation and neighbor advertisement which can effectively avoid the ping-pong effect and handover synchronization effect. NS-2 simulation is also given to show the performance enhancement of the enhanced algorithm compared with the traditional algorithm based on signal power and 802.16g quick handover algorithm.
