RPL路由协议的研究与改进
Study and Improvement of RPL Routing Protocol
摘要
Abstract
RPL routing protocol in non-storage mode,congestion will be caused by accumulation of a large number of Destination Advertisement Option (DAO) and intermediate nodes need larger buffer to store DAO before relaying to their parents.Regarding the issue above,an improved algorithm for RPL routing protocol is proposed,which adjusts the DelayDAO timers by sending the backward pressure message to its children.Thus,controlling the generation and relaying of DAO messages.At the same time,using the multi-frequency characteristics of many existing nodes,the control information messages and data packets are physically isolated.The experiment and analysis show that compared with the traditional non-storage mode of RPL routing protocol,the improved routing protocol reduces the buffer occupancy,and also reduces the network congestion and packet loss during data packet transmission.关键词
