A Framework for joint scheduling and diversity exploitation under physical interference in wireless mesh networks

Recently, interest has arisen in use of realistic interference for transmission scheduling in wireless networks, particularly in mesh networks where is a major concern. In this work, we use the based physical interference model and develop a uniform for transmission scheduling when diverse resources can be exploited. The factors considered multiple (possibly overlapped) channels, directional antennas,translnit power control. We develop an efficient for computing a diversity exploiting schedule on a new network saturation metric. We prove that,uniform random node distributions, the schedule produced our heuristic is within a poly-log factor from optimal a probability that approaches one as network size. Through simulation, we demonstrate the ability algorithm to achieve up to a 10-fold throughput improvement respect to networks without diversity. Our also reveals a number of insights on the ability of exploitation to reduce or eliminate interference.
