摘要： 针对无线传感器网络中节点的能耗和部署问题，提出一种满足覆盖约束的有限可靠路由协议。由工作节点和冗余节点构成节点集，将节点剩余能量值作为节点轮换的参考指标，定义节点工作的有限状态机，并引入一种混合可靠性机制，能在避免产生覆盖漏洞的同时，将丢包率控制在允许范围内。仿真结果表明，该协议能延长网络寿命，降低网络整体能耗。

Abstract: Aiming at the energy consumption and deploy problems in Wireless Sensor Network(WSN), this paper presents a reliable routing protocol of satisfying coverage constraint which includes coverage control and reliable data transmission features. The protocol divides the set of nodes into two parts——working nodes and redundant nodes, defines a finite state machine for them, and introduces a hybrid reliable mechanism to realize the reliability requirements as well as avoid coverage holes. Simulation result shows that protocol can extend the network life time remarkably and decrease energy consumption.
