摘要
无线传感网络由于受能量和通信能力的限制,为了保证感知数据的有效送达,路由方法(协议)的设计显得尤为关键.本文提出了一种基于前向感知因子的能量均衡路由协议FAF-EBRP,它通过感知链路权重和前向区域内的能量密度来决定下一跳节点,并设计了相应的局部拓扑自发重构机制.通过实验对FAF-EBRP和LEACH、EEUC两个典型路由方法(协议)进行了比较,结果表明,FAF-EBRP能使无线传感网络表现出更好的能量均衡性和更长的有效工作时间.
Due to the limited energy and communication ability of nodes in Wireless Sensor Network （WSN） ,it is especially important to design a good routing method （protocol） for WSN in order to make sensed data be transmitted to the receiver effective- ly.A kind of routing protocol based on Forward-Aware Factor for Energy Balance （FAF-EBRP） is proposed in this paper. In FAF- EBRP, the next-hop node is selected according to the awareness of link weight and forward energy density. Furthermore, a sponta- neous reconstruction mechanism for local topology is designed additionally. Based on many experiments, FAF-EBRP is compared with classic LEACH and EEUC method.Experimental results show that FAF-EBRP outperforms LEACH and EEUC, which can bal- ance the energy consumption, prolong the function lifetime of WSN.
