Self-adaptive and energy-efficient MAC protocol based on event-driven

Combined with WSN MAC layer protocol characteristics and design requirements, according to the characteristic of WSN monitoring application requirements, this paper puts forward a method based on event driven MAC protocol. The agreement algorithm is to solve the problem of network congestion and node energy unnecessary consumption cause by a large number of redundant monitoring data transceiver. It is a kind of adaptive low power consumption of the MAC layer protocol, which is pointed out based on theoretical foundation of S_MAC protocol, made use of the event driven mechanism system theory, combined with event driven mechanism and the characteristics of the WSN. It has the periodic dormancy mechanism of S_MAC protocol, in the premise of the reliability data, to reduce data redundancy and communication delay time, improve the overall network throughput, to ensure the safety and reliability of the network, which can greatly extends the node of working time. © 2013 ACADEMY PUBLISHER.
