Revisiting Multi-Channel Communication to Mitigate Interference and Link Dynamics in Wireless Sensor Networks

Multichannel communication has been proposed as alternative to adaptive (single-channel) routing protocols for mitigating the impact of interference and link dynamics in wireless sensor networks. While several studies have advocated features of both techniques (not without running up against contradicting arguments) a comprehensive study that aligns these results is still lacking. This paper aims at filling this gap. The authors present an experimental test-bed setup used to perform extensive measurements for both single-channel and multichannel communication. They first analyze single-channel and multichannel communication over a single-hop in terms of packet reception ratio, maximum burst loss, temporal correlation of losses, and loss correlations across channels.
