This paper proposes a MAC protocol called the Latency MAC (LMAC) protocol for wireless sensor networks. The proposed LMAC protocol aims at minimizing the power consumption caused by the idle listening problem through enlarging the data collection time. This study examines the latency constraint in wireless sensor networks and studies the tradeoff between extra latency and energy-efficiency. In the process of trading latency for energy-efficiency, there are many restrictions. Thus, this study analyzed these limitations and then tries to achieve the best tradeoff between latency and energy-efficiency according to these limitations. By increasing the arrival prediction accuracy of data packets, the simulation results show that the LMAC protocol indeed help the sensor nodes to consume less energy, especially for the wireless sensor networks with loose latency constraints or light traffic load.
