摘要：With the development of IOT (things of internet), people propose more and more requirement about the wireless sensor networks performance for its key technology. It not only needs to meet the reliability of the networks, but also put forward higher requirement of the network life. A key factor influencing the network life is the network energy-limited. Therefore, energy-saving has become a key problem for the wireless sensor networks communication protocol design. an energy-saving MAC protocol based on network load mutations is designed. The protocol considers the redundancy problem between the sensor nodes data, takes different scheduling methods for different levels of nodes. A cording to the network load mutation, dynamically adjust to the detective and dormancy time. This method solves the unfairness of the network energy and delay, and can better satisfy changes in the complex network environment .
