Deployment of multi-hop relays in WiMax based cellular networks is considered as a cost effective solution to increase the coverage area of base station and also to improve the network capacity with high quality short links. Scheduling became a challenging task in these multi-hop relay wireless cellular networks of IEEE 802.16j standard. The researchers proposed a Q-aware scheduling algorithm in which back-pressure flow control mechanism is used to reflect current Q size of the relays and considered high back-pressure links to include in concurrent transmission scenarios, to maximize the throughput.
