Abstract :
Wireless sensor networks (WSN) have been widely used in many important areas. Medium access control (MAC) protocols have a significant influence on the function and performance of WSN. In existing protocols such as sensor MAC (SMAC), the sensor nodes reduce energy consumption by introducing an active/sleep duty cycle, which always leads to more control packets. These control packets waste a lot of energy. Other contention-based MAC protocols either cannot solve the idle listening or fail to consider the complexity of the protocol. Based on SMAC, we propose a novel contention-based MAC protocol, which decreases the control packets by modifying the control packets message and canceling time synchronization. The simulation result indicates that the performance of our protocol is much better than that of SMAC protocol in energy consumption.
