基于事件优先级的网络介质访问控制协议

摘要

针对如何延长智能雷场网络生存期的问题，提出了一种基于事件优先级的网络介质访问控制协议。该协议改进了网络介质访问控制层的基础结构以及设定时隙算法，具有短延迟的实时性、信道占用分级的竞争性和节能性等特点。仿真结果表明：该协议既能保证在发现事件发生的情况下第一时间做出准确反应，同时也能保证无事件发生时区域监测模式下的网络运行在低能耗状态下，延长网络生存期。%In order to prolong the network survival time of intelligent minefield,this paper came up with a kind of network media access control protocol based on event priority (EP-MAC).The protocol improved the basic structure of media access control layer and set time slot algorithm.It had several features such as low latency and real-time,the competition of channel occupation classification and energy saving.The simulated results showed that EP-MAC protocol could guarantee to make accurate reaction when events happened,meanwhile,it could also ensure that the network was in the operation of low energy consumption when no events happened,to prolong the network survival time.
