低功耗有损网络路由协议研究

Research on Low Power Loss Network Routing Protocol

随着物联网的发展,低功耗有损网络拥有了广泛的应用场景.低功耗有损网络具有有损性和不稳定性,传统路由协议难以应用于低功耗有损网络,IETF针对这一问题提出了基于IPv6架构的RPL路由协议.对RPL路由协议的相关术语和协议原理进行了研究,并对RPL路由协议在节点静止环境和节点移动环境的性能进行了仿真分析.实验结果表明,相对于节点位置固定的静止环境,RPL路由协议在节点移动环境中网络平均寿命较短.

With the development of the internet of things,low-power lossy networks have a wide range of application scenarios.Low-power lossy networks are lossy and unstable.Traditional routing protocols are difficult to apply to low-power lossy networks.IETF proposes an RPL routing protocol based on the IPv6 architecture for this problem.The related terms and protocol principles of RPL routing protocol are studied,and the performance of RPL routing protocol in node static environment and node mobile environment is simulated and analyzed.The experimental results show that the RPL routing protocol has a shorter average network life in the node mobile environment than the stationary environment where the node position is fixed.
