Efficient Resource Allocation for Energy Conservation in Uplink Transmissions of IEEE 802.16j Transparent Relay Networks
By introducing the relay capability, the IEEE 802.16j standard is developed to improve the WiMAX performance. Under the transparent mode, existing studies aim at improving network throughput by increasing the transmission rates of Mobile Stations (MSs). However, the authors show that using higher rates will let MSs consume more energy. In the paper, they define an Energy-conserved Uplink Resource Allocation (EURA) problem in 802.16j networks under the transparent mode, which asks how to arrange the uplink resource to satisfy MSs' requests and minimize their energy consumption.
