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(More)
Recently, relay agents selection schemes were introduced to support downlink multicasting in WiMAX single frequency networks. Such schemes were devised to work cooperatively in order to facilitate reliable Mul-ticast Broadcast Multimedia Services (MBMS) traffic delivery over wireless channels without any consideration to mobile relay agents' battery energy(More)
