A distributed broadcast protocol of wireless sensor networks based on dynamic multi-channel MAC protocol

Abstract

Multi-channel MAC protocols have recently attracted much attention as it is considered a promising direction for improving the performance of wireless sensor networks. But most of these protocols didnt consider the performance of broadcast. The traditional broadcast is difficult to work in multi-channel wireless sensor networks using dynamic channel assignment. In this letter, we proposed a distributed solution to broadcast by multiple unicast based on a broadcast tree. The tree can be built through sending broadcast training packages several times before broadcast. The simulation results showed that this broadcast protocol has good broadcast latency metric. © 2013 Springer-Verlag.
