Paper Title
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. Keywords - Cooperation, Relay selection, Fairness, Lifetime.
