The Adaptive Scheme and Relationship Between Traffic Load and Optimal Duty Cycle Based on Best Traffic Efficiency in S-MAC

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. From the view of energy efficiency and large simulation test, this paper analyses the relationship between traffic load and duty cycle in S-MAC and gets the relationship on known MAX energy efficiency. According to the relationship, this paper proposes the adaptive A-SMAC which can confirm best abundant evaluation based on service flow. It shows that A-SMAC can improve the performance effectively and have good compatibility.
