摘要
As a classic protocol based on the MAC protocol in wireless sensor networks, the S-MAC protocol has been arousing the people's widespread interests. According to the S-MAC data frame structure and signaling characteristics, this paper puts forward a blast-off power control mechanism based on S-MAC; modifies the competitive mechanism of the S-MAC protocol, and provides the protection to the nodes with less energy. This text is called the ES-MAC to the S-MAC protocol that used these two kinds of mechanisms, simulation test shows that ES-MAC can effectively reduce energy consumption, and improves energy efficiency; finally, it introduces the access priority in S-MAC protocol, increases support which access to different priority nodes. Through these processes, the S-MAC protocol function is improved effectively.
