AODV 路由算法在无线传感器网络中的设计与仿真 Design and Simulation of AODV Routing Algorithm in Wireless Sensor Network摘 要容错是 WSN 中的主要问题之一，因为它在实际部署的环境中变得至关重要，在该环境中，网络稳定性和减少的不可访问时间非常重要。因为无线传感器网络通常应用于恶劣的环境，传感器的易损性和无线通信容易受到环境影响导致了无线传感器网络的不稳定性。如果在数据在多节点传输的过程中其中一个节点故障则会引发链接故障无法传输数据。本文中，提出在 WSN 中使用的 Ad hoc 按需距离矢量（AODV）路由协议设计一种容错的多径 AODV 算法，即基于多径的MD-AODV 路由协议，来解决可靠性问题与效率问题。本文为网络中的每个节点创建备份路径来设计和实现备份路由方案。本协议分为一跳最短路径和次短路径同时传输数据包，当节点无法通过最短路路径传送数据包时，备用路由立即成为下一个数据包传送的新主路径没有任何中断时间，使得发生节点故障时减少丢包率和减少重新开始路由发现的次数。此外，该提议的路由协议提高了吞吐量和平均端到端延迟，还有后期的网络开销优化。所以，实现了网络的可靠性，可用性和可维护性。仿真表明，所提出的路由方案优于 AODV 路由。关键词：AODV 算法；无线传感器网络；网络仿真 ；路由算法AbstractFault tolerance is one of the main problems in WSN, because it becomes very important in the actual deployment environment, in which network stability and reduced inaccessible time are very important. Because wireless sensor networks are usually used in harsh environments, the vulnerability of sensors and wireless communication are easily affected by the environment, which leads to the instability of wireless sensor networks. If one of the nodes fails in the process of data transmission, it will lead to link failure and unable to transmit data. In this paper, a fault-tolerant multipath AODV algorithm, md-aodv routing protocol based on multipath, is proposed to solve the reliability and efficiency problems. This paper creates a backup path for each node in the network to...
