无线传感器网络是由大量部署在监测区域内的微型智能传感器节点,以无线通信方式,组成的一个多跳自组织的网络。本文研究并设计了一种新的多路径路由协议MPRP,并进行了仿真及与AODV协议的比较。该协议充分考虑了网络中节点到基站端到端的延时与节点的剩余能量等因素。这种设计在端到端的延时、节点的剩余能量、控制广播包的个数都优于AODV。实验结果表明:该多路径路由协议MPRP具有控制的广播数量少、节能效率高等特点。 Wireless sensor network is a multi-hop self-organizing network consisting of a large number of micro-intelligent sensor nodes deployed in the monitoring area and wireless communication. In this paper, a new multi-path routing protocol, MPRP, is researched and designed and compared with the AODV protocol. The protocol takes full account of the network end-to-end node to base station delay and node remaining energy and other factors. The end-to-end delay of this design, the node’s remaining energy, the number of control broadcast packets are better than AODV. The experimental results show that the multi-path routing protocol MPRP has fewer features such as less broadcast and higher energy efficiency.
