Abstract :
This paper proposes a distributed relay assignment scheme with interference limitation for industrial wireless networks that exploits cooperative diversity to cope with problems of wireless channels and to enhance the reliability of data transmission. By combining the selection and incremental relaying schemes and by taking the channel status information and queue length at each node into account, the cooperative scheme improves the packet dropped ratio and end-to-end delay due to retransmissions. In addition, this paper also investigates the interference problem produced by the relay nodes. Simulation results conducted to evaluate the performance of the proposed scheme indicate that it effectively enhances the network performance in terms of the packet delivery ratio, energy consumption, and overall packet delay.
