In present Wireless Sensor Network(WSN) MAC protocol research,it is generally assumed that node is static.This paper researches the influence of mobility on current WSN MAC protocols,and proposes Adaptive Synchronization Activation(ASA) algorithm.With the help of global time information,ASA avoids the influence that the mobility has to activation/sleep schedule mechanism in WSN MAC protocol.Simulation results show that ASA algorithm displays better performance in the mobile environment,and its packet delivery rate and energy efficiency is better than S-MAC protocol.
