摘要

Under this cooperative communication, the selection of relay node significantly affects the performance of wireless networks. The previous researches optimised the Max-Min Fairness (MF), which may drastically decrease the network throughput. Thus, this paper studies the fairness-aware relay assignment to improve the network throughput. First, we develop the PFRA algorithm, which assigns the relays by saturated bipartite matching, to reach the proportional fairness. Next, a distributed version of Proportional Fairness Relay Assignment (PFRA) algorithm is also proposed. Moreover, lexicographical Max-Min fairness is achieved by Lexicographical Fairness Relay Assignment (LFRA) algorithm. We formally prove the optimality of above three algorithms. The experimental results show the efficiency of the proposed algorithms.
