Near-Optimal Relay Station Placement for Power Minimization in WiMAX Networks
In the IEEE 802:16j standard, the relay station has been introduced to increase the coverage and the throughput of WiMAX networks. The placement of the relay station plays a critical role in the system performance and therefore draws tremendous attention from the research community. In this paper, the authors study the relay station placement problem in the WiMAX network, with the cooperative communication as the relaying strategy. In particular, given a base station and a set of subscriber stations, they determine the location of a relay station, and the set of subscriber stations using the relay station.
