The deployment of the relay stations is one of the most important issues that determine the network throughput. In literature, some deployment strategies have been proposed. However, none of them follows the frame structure designed in IEEE 802.16j draft. Furthermore, they did not consider that the bandwidth constraint of BS, RS and MS will be changed with the deployed location of relay. Given a base station, k relay stations, and a region that can be full covered by the base station, this paper proposed a relay deployment mechanism that determines the deployed locations of RSs so that the bandwidth requirement of MSs can be satisfied while the network throughput can be significantly improved. Experimental study reveals that the proposed relay deployment mechanism can efficiently determine the locations for relay deployment and improve the network throughput.
