Throughput improvement by network coding and spatial reuse in wireless mesh networks

Abstract

It is understood that the performance of network coding (NC) is largely dependent on link scheduling schemes, and greedy NC may in fact reduce network throughput due to the reduction of spectrum spatial reuse. In this paper, we study the interplay between NC and spatial reuse, and present a NC-aware link scheduling scheme to increase network throughput. Then, we propose an adaptive power control scheme to decrease interference so that NC and spatial reuse can be complementary in throughput improvement. Simulation results demonstrate that NC and spatial reuse are suitable for different network environments, and our proposed schemes can optimize network throughput by taking full advantage of the superiorities of both NC and spatial reuse in different network topologies.
