Delay Analysis of Maximum Weight Scheduling in Wireless Ad Hoc Networks Citation

This paper studies delay properties of the wellknown maximum weight scheduling algorithm in wireless ad hoc networks. We consider wireless networks with either onehop or multi-hop flows. Specifically, this paper shows that the maximum weight scheduling algorithm achieves order optimal delay for wireless ad hoc networks with single-hop traffic flows if the number of activated links in one typical schedule is of the same order as the number of links in the network. This condition would be satisfied for most practical wireless networks. This result holds for both i.i.d and Markov modulated arrival processes with two states. For the multi-hop flow case, we also derive tight backlog bounds in the order sense.
