Abstract :
Multiuser detection based Medium Access Control (MAC) can give significant gains in throughput and Quality of Service (QoS) when applied to wireless Ad Hoc networks. To realize these gains, one has to implement a distributed neighborhood scheduling that provides the desired performance objectives. In this paper, we propose an approach for analyzing and comparing optimal or suboptimal distributed neighborhood scheduling schemes with different objectives. Then, we demonstrate the viability of this approach by implementing a scheduling scheme that uses Start Time Fair Queuing (STFQ) algorithm and by comparing its performance to a published suboptimal distributed scheduling for multiuser detection based MAC. In particular, the numerical results show that the delay performance of the priority voice packets can be significantly improved by using STFQ algorithm.
