This paper strengthens the application of adaptive listening technology in S-MAC.When the nodes have no data to process, they are in dormancy state for most of the time, while when the data is coming, they become active quickly and participate in data transmission actively.The nodes which can feel the transmission is just around will participate in adaptive transmission as much as possible and make continuous adaptive listening within one dormancy period.In this way, realize the purpose of deceasing end to end delay greatly on the basis of not increasing additional energy consumption.For applications which are sensitive to system response time, the improved S-MAC is with greater application value.
