Abstract
In recent years, full-duplex communication has been investigated in wireless networks to improve the quality of transmission service. Most existing work focused on the physical layer, with little consideration of the upper layers. In this paper, we address the issue of joint routing and link scheduling in software-defined full-duplex wireless networks, where an exclusive SDN controller node is involved. Firstly, we formulate the problem as an optimization problem, which tries to maximize the total throughput of the network. Due to the NP-hardness of this problem, we propose a heuristic algorithm that jointly consider the routing selection and link scheduling. For routing selection subroutine, we propose the minimum-cost routing algorithm (MinCostRo for short). We evaluate the performance in MATLAB, and compare it with the DRPA routing algorithm and the minimal maximal interference routing algorithm (MinMaxRo for short). It can be found that MinCostRo performs better than the two existing methods.
