Executive Summary

This paper presents a fixed relay nodes random access protocol which based on time division multiple access. The protocol uses the users and relay nodes cooperation retransmission mechanism to solve the multi-user access collision problem. The key idea is to use non-persistent monitor way for random access, guarantee a certain percentage of throughput, then re-use the network resources through the selective retransmission to obtain diversity. When the data packets happen collision, the receivers can establish the linear simultaneous equations according to the non-fading correlation coefficient, solve it and restore the original data.
