摘　　要：针对工作周期(DC)的无线传感网络(WSNs),研究人员试图利用任播技术降低传输时延和能耗,并进行了深入研究。为此,提出新的能效任播路由(EEAR)。相比现存的任播路由指标,EEAR路由引用新的任播路由指标,称为期望能耗(EEC)。利用EEC合理地选择转发节点集,进而最小化传输数据包的能耗。仿真结果表明,提出的EEAR协议降低了能耗,同时,也维持了合理的时延和高的数据包传递率。Aiming at the Wireless Sensor Networks(WSNs)of Duty Cycle(DC),the researchers have attempted to reduce transmission delay and energy consumption by Anycast technology,and have conducted in-depth research.An Energy Efficient Anycast Routing(EEAR)protocol is proposed in this paper.EEAR adopts a new Anycast routing metric called Expected Energy Consumed(EEC)that is contrary to previous Anycast routing metrics.By using the new Anycast routing metric,the forwarder set is selected reasonably and the expected energy consumed can be minimized along the path of a packet.Simulation results show that EEAR consumes less energy than similar existing protocols,while maintaining a comparable delay and high delivery rate.
