Performance analysis of predictive trigger algorithm for mobile wimax networks

Abstract

A major consideration for mobile WiMAX is Seamless Handover. Cellular-based standards have the advantage of many years experience in handover for voice calls, while for broadband mobility in itself is no mean feat, and handover is still a challenge. IEEE 802.16e (Mobile WiMAX) is a wireless metropolitan area network standard with high transmission speed and great coverage. This work will address the handover process; an important issue of Mobile WiMAX system. This thesis considers the importance to have the correct handover initiation process. By using a predictive algorithm, in hands of the threshold that triggers the handover process based on RSSI. We study in this thesis the intracellular and intercellular handover process in Mobile WiMAX system. We focus in particular on the impact of use a predictive trigger algorithm in order to ensure a success handover process. We demonstrate that using a predictive algorithm offers a significantly advantage over the traditional algorithm of handover process.
