Transmission power control in multi-hop wireless networks is a challenging problem due to the effects that different node transmission powers have across the layers of the protocol stack. In this paper, the authors study the problem of transmission power control in IEEE 802.16 mesh networks with distributed scheduling. They consider the effects of transmission power control on the link-scheduling performance when a set of end-to-end flows established in the network are given. The problem is approached by means of the stability region of the link-scheduling policy. Specifically, the stability region is adapted using transmission-power control to the paths of the flows.
