摘　　要：对大规模无线传感器网络(WSNs)的路由协议进行了研究,针对大规模WSNs密集实时数据采集这一应用模型所存在的传送实时数据延时长、传送大量密集数据能耗大的问题,在LEACH-C协议的基础上,提出一种多优先级自适应(MPA)分簇路由协议。该协议针对不同数据采用多优先级服务策略,同时引入基于休眠/活动节点对的改进TDMA机制。仿真结果表明:MPA协议较LEACH-C协议有效地减少了传输实时数据的延时,并且为网络提供了很好的能量有效性。更适合于采集密集实时数据的大规模部署的WSNs。Routing protocol in a large scale wireless sensor networks（WSNs） is researched. Long latency of datatransmitting and high energy consumption are main problems of the large-scale wireless sensor networks which is used for gathering data real-time. A multi-priority adaptive （MPA） cluster-based routing protocol is proposed to settle the two problems above. Aimed at different data, multi-priority is adopted and improved TDMA schedule based on the sleep/active nodes pair is introduced. Simulation results show that MPA protocol reduces the timeelay of real-time data transmitting effectively. Besides,it also provides a good energy efficiency to the networks. The MPA protocol is suitable for the large-scale wireless sensor networks.
