摘　　要：针对煤矿无线传感器网络数据流特点,设计了一种基于节点地理位置信息、集成MAC和路由的无线传感器网络可靠数据传输协议。该协议采用概率性唤醒工作方式,根据本地节点的连通度、节点自身的剩余能量信息和区域事件发生概率选择转发节点,同时引入备用节点,在主节点发生故障时自动转换为主节点进行数据转发,保证数据可靠传输。仿真结果表明,该协议能够降低无线传感器网络节点能量消耗,保证数据传输的实时性,提高数据传输的可靠性。A reliable data transmission protocol of wireless sensor network was proposed according to characteristics of data flow of coal mine wireless sensor network,which was based on position information of sensor nodes and integrated MAC and routing.The protocol uses probabilistic awakening work mode,and selects forwarding node according to connectivity of local node,dump energy of the node and occurrence probability of regional event.Meanwhile,the protocol introduces standby node to forward data when main node is invalid,so as to ensure reliable data transmission.The simulation results show that the protocol reduces energy consumption of node in wireless sensor network and improves real-time performance of data transmission as well as reliability.
