Abstract

Abstract:

Aiming at solving the problem that information about the distribution of network traffic load cannot be correctly captured by interferer neighbors count (INX) routing metric, an interference and regional load aware (IRLA) routing metric for wireless mesh networks was proposed. Average competition degree was used to describe the competition degree for the same channel among interferer links and the dispersion degree of traffic load on interferer links. The information was utilized to guide the routing selection for avoiding heavy traffic load regions and achieving network load balance effectively. Analysis and NS-2 simulation show that the proposed routing metric can not only improve network throughput dramatically, but also reduce end to end delay and packet loss ratio, and it can even enhance the network performance in heavy load environment.
