Cooperative protocols for multiple-source multiple-relay wireless networks

International Journal of Sensor Networks (IJSNET), Vol. 4, No. 4, 2008

Abstract: In this paper, we study the cooperative communications in wireless systems with n_s source nodes, n_r relay nodes and single destination node. We propose cooperative protocols and analyse the system performance of the cooperation systems. For n_s = 1, n_r > 1, the nodes cooperate in a repetition way. The impact of the detection error at the relay node on the system performance is analysed, and then a relay selection protocol is proposed to compensate for such effect. For n_s > 1, n_r > 1, we propose a cooperative coding protocol, in which the relay nodes not only decode and forward the symbols from the source nodes, but also encode the incoming symbols according to the pre-assigned cooperative code. This brings higher efficiency and flexibility compared with the repetition-coded cooperation system with single source node. The analysis and the simulation results demonstrate that the proposed system achieves full diversity order.
