A channelization protocol for multi-hop wireless sensor networks using frequency division multiplexing

Abstract

We present a channelization protocol based on frequency division multiplexing to enable fast, reliable, multi-hop data transmission with minimal protocol overhead in wireless sensor networks. The protocol enables data transmission to occur at a high rate by eliminating intra-path collisions along a multi-hop routing path. This is achieved by staggering communication frequencies such that no two adjacent nodes transmit data at the same radio frequency. We describe the design and implementation of the protocol and present extensive experimental results to validate its efficacy.
