无线传感器网络(WSN)中,由于无线链路的链路质量问题,经常有传递失败导致重传耗费能量的现象出现.传统任播路由协议只以路由距离作为路由判据,而没有讨论链路质量问题,将其应用在WSN中会造成路由权重设置不合理.提出了基于链路质量的WSN任播路由协议,该协议在讨论链路质量的计算之上,以能耗均衡和系统能耗最小这两个因素决定任播路径的路由权重,并以参数α采权衡两者之间的关系.实验证明,在WSN中,相比传统任播路由协议,该协议能更有效地均衡能耗,减少系统能耗,从而优化网络生存期.

In Wireless Sensor Networks(WSN),there is the probability of transmission failure and energy waste for retransmission because of link quality problem.Routing criteria of conventional anycast routing protocols are based only on routing distance but not in consideration of link quality problem,it will lead to unreasonable routing weight setting if we apply those protocols in WSN.A WSN anycast routing protocol based on link quality was proposed.Calculation of link quality was discussed.The routing criterion of our protocol is based on the hybrid of load balancing and minimum total energy cost,and we balanced the two factors by parameter a.In contrast to conventional anycat routing protocols,experiment results show that performances in WSN are improved in terms of energy balancing and network energy consuming hence network lifetime is optimized.
