Duty cycled WSN MACs with fixed periodic wake up and sleep intervals work well for periodic networks. For event driven networks where events can occur at anytime, fixed duty cycles introduce delay waiting for the next wakeup time and power wastage idle listening in the active state. SMDP-MAC, a Semi Markov Decision Process based event driven MAC for WSNs is presented in this work. Simulation results show an improvement in average power consumption and delay for SMDP-MAC compared to LIMAC, a state of the art WSN MAC protocol.
