| Abstract | This paper addresses the problem of fairness portioning in multi-channel, multi-radio wireless mesh networks by applying the integration of network coding and directional antennas techniques. It is the fact that Network coding can increase transmission efficiency in wireless networks. Moreover, directional antennas, concentrating the beam energy at a specified direction, can also improve the network performance. However, the interacting of the two techniques is scarcely studied. In this paper, we propose an analytical model to figure out the incorporation of directional antennas and network coding schemes to improve fairness provisioning. To address the problem, we first present integer linear programming formulation optimizations, which maximize the throughput while satisfying the fairness requirements. Based on solving the linear programming, we propose a link scheduling and channel assignment with a heuristic method. The evaluations show that the algorithm we propose can effectively take advantages of the number of channels and radios. In addition, it shows that our algorithm outperforms other algorithms which either coding-oblivious or directional antenna-oblivious. |
