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, we study the relay station placement problem in the WiMAX network, with the cooperative communication...
The recently emerging WiMAX (IEEE 802.16) is a promising telecommunication technology to provide low-cost, high-speed and long-range wireless communications. To meet the growing demand for throughput, Relay Station is introduced by IEEE 802.16j to relay traffic for Subscriber Stations. By incorporating Cooperative Communications scheme in WiMAX, we can further improve the network capacity. In this...
The IEEE 802.16 standard supports the multi-hop mesh mechanism, which focuses on high throughput, fast and cost-effective deployment. The standard defines the scheduling scheme in mesh mode, and many researchers have contributed greatly to this area. However, most of the existing research work is designed for single-radio single-channel environment and some heavy traffic nodes become the bottleneck...
