Abstract
Recently, analytic models proposed to evaluate the energy consumption of sensor-medium access control (S-MAC) protocol, one of the well-known MAC protocols for wireless sensor networks (WSNs), are based on the model for the IEEE 802.11 MAC protocol. Since the S-MAC protocol has distinct differences from the IEEE 802.11 MAC protocol, however, those differences should be reflected in the analytic evaluation. For this, we first present a Markov chain model for the single-hop S-MAC protocol under un-saturated condition. Then, by considering competing sensors in shared channel, we derive the energy consumption of the S-MAC protocol. Finally, numerical results for a practical sensor mote are shown
