Abstract

Cooperative communication has known as an eective solution to deal with the channel fading as well as to improve the network
performances. Further, by combining the cooperative relaying technique with the physical-layer network coding (PNC), cooperative networks will obtain more benefits to improve the throughput and network resource utilization. In order to leverage these benefits in this paper, we propose a PHY-MAC cross-layer cooperative protocol which can support PNC for multi-rate cooperative wireless networks with bidirectional traffic. The design objective of the proposed protocol is to increase the transmission reliability, throughput, and energy efficiency, and reduce the transmission delay. Simulation results show that the proposed protocol outperforms the previous cooperative protocol as well as the traditional protocol in terms of the network performance.
