In wireless mesh networks (WMNs), TDMA based link schedulingcan allow multiple concurrent transmissions, resulting in throughput improvements. In this paper, we identify certain link characteristics which reduce achieved spatial reuse and increase schedule length. It is shown that certain links (called loners) based on their length and position, introduce inherent difficulty in scheduling them with...
In this paper, we consider the problem of topology control by joint power control and routing to maximize the network throughput in wireless mesh networks. First, we present two mathematical formulations of the joint power control and routing problem according to two different definitions of network throughput: the total throughput and the minimal per-node throughput. To reduce the computation cost,...
What is the fastest rate at which we can collect a stream of aggregated data from a set of wireless sensors organized as a tree? We explore a hierarchy of techniques using realistic simulation models to address this question. We begin by considering TDMA scheduling on a single channel, reducing the original problem to minimizing the number of time slots needed to schedule each link of the aggregation...
