Adjacent Channel Interference Reduction in Multichannel Wireless Networks Using Intelligent Channel Allocation

Executive Summary

The performance of a multichannel, multi-radio wireless network is often limited by interference due to concurrent transmissions on the same and adjacent channels. These interference effects may be either due to simultaneous traffic activity by the multiple radios within a node or due to transmission by neighboring nodes. In this paper, the authors discuss simple local-balancing and interference-aware channel allocation algorithms for reducing the overall interference in the network. They evaluate the relative performance of the authors' algorithms using actual implementations on a multichannel, multi-radio testbed.
