Abstract:

For multi-channel duty-cycled wireless sensor networks, the minimum delay broadcast problem was proved to be NP-hard. Two new concepts of candidate active conflict graph and feasible active conflict graph were presented. A Low delay broadcast algorithm called efficient broadcast algorithm was proposed based on these two new concepts. Analysis shows that this algorithm has a small approximation ratio. Simulation shows at the same time that efficient broadcast algorithm improves the broadcast delay efficiently compared with the existing work.
