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。 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.
