The paper presents a simple probabilistic analysis of the energy consumption in preamble sampling MAC protocols. The authors validate the analytical results with simulations. They compare the classical MAC protocols (B-MAC and X-MAC) with LA-MAC, a method proposed in a companion paper. Their analysis highlights the energy savings achievable with LA-MAC with respect to B-MAC and X-MAC. It also shows that LA-MAC provides the best performance in the considered case of high density networks under traffic congestion.
