Abstract

The directional 60GHz mmWave WPAN system can support concurrent transmissions owing to reduced interference among links. In this paper, a simple but effective STDMA scheduling scheme based on IEEE 802.11ad is proposed. In order to take user fairness into account in the concurrent link scheduling, an adjustment factor is first introduced, and a link scheduling scheme with low complexity is designed on that basis. Simulation results show that a tradeoff between fairness and throughput is achieved by the use of the adjustment factor. Although the complexity of the proposed algorithm is much lower than that of exhaustive search, nearly the same throughput can be achieved in the extreme case.
