Abstract

In this paper, we propose an energy-efficient cooperative multicasting scheme for Multicast Broadcast Multimedia Services (MBMS) offered by WiMAX by properly selecting relay agent (RAs) based on their location, channel condition. By exploiting the channel state information (CSI) and the location based service (LBS), the nearest neighbor protocol is implemented to achieve significant improvement in the system performance. The number of RAs varies in accordance to channel conditions and is treated on a frame-per-frame basis. This approach considerably reduces the amount of energy consumed as proven by simulation models, providing a lower cost coverage solution, with no dereliction in achieving high throughput or reliable transmission for all group members.
