摘要
针对无线传感器网络(WSN)中传统多径路由协议不能满足网络可靠性和能耗需求,提出了一种基于可靠性评估和路径自适应配置的新型多径路由协议。首先,通过因子分解法将WSN建模成有序二元决策图(OBDD)表示模型,并以此根据链接可靠性来评估网络可靠性;然后,提出一种可靠性感知的自适应多径路由配置机制(RA-MRC),根据网络可靠性和路径权重,适当地激活或失活一些路径,以此来满足预定的网络可靠性,并降低网络的传输和能量开销。仿真实验结果表明,在网络可靠性、网络开销、传输时延等方面,该方案比传统固定路径数量的路由协议具有明显提升。
For the issues that the traditional multipath routing protocols in wireless sensor networks(WSNs)can’t meet the network reliability and energy consumption requirements,this paper proposed a new multipath routing protocol based on reliability evaluation and path adaptive configuration.Firstly,it modeled the WSN as an ordered binary decision diagram(OBDD)representation model by factorization,and evaluated the reliability of the network according to the link reliability.Then,it proposed a reliability-aware adaptive multipath routing configuration(RA-MRC)mechanism,which used to properly activate or deactivate some paths according to network reliability and path weight,so as to meet the predetermined network reliability and reduce network transmission and energy costs.The simulation results show that the proposed scheme has a significant improvement over the traditional fixed path routing protocol in terms of network reliability,network overhead and transmission delay.
