An incentive-based fairness mechanism for multi-hop wireless backhaul networks with selfish nodes

Abstract

In this paper, we study the fairness problem in multi-hop wireless backhaul networks in the presence of selfish transit access points (TAPs). We design an incentive-based mechanism which encourages TAPs to forward data for other TAPs, and thus eliminates the location-dependent unfairness problem in the backhaul network. We prove the correctness and truthfulness of the proposed mechanism, and evaluate its performance via ns-2 simulations. The results show that the proposed mechanism achieves fairness even when there are idle TAPs in the network.
