Joint Power Control and Scheduling for Minimizing Broadcast Delay in Wireless Mesh Networks
In this paper, the authors address the problem of joint power control and scheduling for minimizing broadcast delay in wireless mesh networks. Given a set of mesh routers and a routing tree rooted from the gateway node, their task is to assign power for each relay node and compute an optimal transmission schedule such that the longest delay for a packet broadcast from the root node to all the other routers is minimized. They consider rate adaption in their scheme. This is a difficult issue.
