Abstract
This work presents a new MAC protocol for WSNs that combines an unscheduled channel access, based on lowpower listening, with an opportunistic scheduled wake up after transmissions mechanism. The proposed MAC provides a good tradeoff between energy consumption, complexity and performance in terms of throughput and delay. It achieves the benefits of scheduled MAC protocols without the cost of maintaining and sharing the schedule, as well as the low consumption and simple operation of unscheduled MAC protocols.
