Reliable WiMAX Multicast Applications

Abstract

This study proposes a reliable multicast mechanism for WiMAX applications. The proposed mechanism is based on the core-based tree data forwarding architecture and IGMP group management, and can handle the data sending to the receivers successfully with error recovery and fast-handoff. A WiMAX multicast mechanism with mobility applications is also presented. Simulation results indicate that the proposed multicast mechanism can reduce the network load by about 35% and the average delay by about 29%.
