无线传感器路由协议由于受到硬件的限制,节点的能量、处理能力、存储能力都受到极大的制约.RPL(Routing Protocol for Low pow er and Lossy Netw orks)协议是工作在IPV6无线传感器网络网络层的路由协议,由IETF(Internet Engineering Task Force)的ROLL(Routing Over Low-pow er and Lossy netw orks)工作组专门为低功耗有损网络而提出的距离矢量路由协议.详细介绍AODV路由协议,阐述了RPL路由协议的相关术语、协议原理和拓扑结构;利用Contiki操作系统和其自带的仿真器Cooja模拟了RPL路由协议的运行过程,包含采用3种控制消息进行向上路由和向下路由的建立的过程,RPL路由协议的拓扑构建过程,数据包路由过程和Trickle定时器的应用;通过与传统WSN路由协议AODV在数据递交率、端到端时延等性能参数的仿真对比,验证RPL路由协议在低功耗有损网络中具有较高的性能.
Due to the limitation of hardware, wireless sensor routing protocols greatly limit the energy, processing power and storage capacity of the nodes.RSP (Routing Protocol for Low-Power and Lossy Network) protocols work at the network layer of the IPV6 wireless sensor network The routing protocol is a distance vector routing protocol specially proposed by the Working Group of Routing Over Low-Power and Lossy Networks (IETF) for Low-Power Lossy Networks. The AODV routing protocol is described in detail RPL routing protocol related terms, protocol principles and topology; using Contiki operating system and its own simulator Cooja simulated RPL routing protocol operation, including the use of three kinds of control messages for the up and down routing establishment , RPL routing protocol topology construction process, packet routing process and Trickle timer application; Through the comparison with the traditional WSN routing protocol AODV performance parameters such as data delivery rate, end-to-end delay, verify the RPL routing protocol Low-power lossy network with high performance.
