This paper analysis delay properties of the well known maximum weight scheduling algorithm in wireless adhoc networks. We consider wireless networks with either one hop 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 has the same order with the number of links in the network. This condition would be satisfied for most practical wireless networks. This paper focuses themethod is general and it can be used to derive bounds for the sum of even higher moments of the stationary queue sizes. However,for the approximate MWS policy, the bounds for the second or higher moments are only valid when the average arrival ratevector is limited to a subset of the capacity region that depends on the order of the moment.
