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.
