摘要：

MAC protocol controls the activity of wireless radio of sensor nodes directly so that it is the major consumer of sensor energy and the energy efficiency of MAC protocol makes a strong impact on the network performance. TDMA-based MAC protocol is inherently collision-free and can rule out idle listening since nodes know when to transmit. However, conventional TDMA protocol is not suitable for event-driven applications. In this paper, we present ED-TDMA, an event-driven TDMA protocol for wireless sensor networks. Then we conduct extensive simulations to compare it with other MAC protocols such as BMA, S-MAC, and LMAC. Simulation results show that ED-TDMA performs better for event-driven application in wireless sensor networks with high-density deployment and under low traffic.
