The IEEE 802.16j standard defines mobile multi-hop relay wireless cellular networks. Introduction of relays in WiMAX networks pose new challenges along with the advantages of high throughput and improved coverage area. Thus scheduling plays a crucial role in Mobile Multi-hop Relay (MMR) wireless networks. The queue aware scheduling algorithm maximizes the throughput by considering queues at Base Station (BS) and Relay Station (RS) as well along with concurrent transmission technique. In queue aware scheduling, as all the arrived packets are queued up in FCFS manner, the high priority packets are obviously delayed.
