A Novel Multiple Relay Selection Algorithm in Cooperative IEEE 802.11 Wlan
Cooperative communication techniques have recently emerged as promising solutions for some challenges of
wireless communications. The main challenge is relay selection algorithms according to the benefits expected from the
cooperation. In this paper, we propose a new scheme of relay selection in MAC protocol of IEEE 802.11 standard which
exploit multiple relay nodes during the cooperation. In proposed scheme, every relay node participates in cooperation
proportionally to its provided cooperation gain. Simulation results demonstrates that our proposal improve the network
performance in terms of throughput, fairness and network lifetime.
