摘要
低功耗有损网络LLNs(Low-Power and Lossy Networks)中,RPL路由协议可以减少能耗和延长网络生命周期,但是负载的不均衡严重影响了RPL路由协议的性能。据此,提出了一种优化的RPL路由协议—WLB-RPL。该协议以节点剩余能量以及节点平均邻居距离为权重计算剩余级别,并通过动态调整通信半径完成路由构建,以均衡能量。仿真结果表明,改进后的路由协议可以对之前的负载均衡进行更好的优化,达到了理想的效果。
In the current Low-Power and Lossy Networks,the RPL routing protocol can reduce network energy consumption and extend the network life cycle.However,load unbalance has significant impacts on the performance of the RPL routing protocol.So,an optimized RPL routing protocol WLB-RPL is proposed.The protocol calculates the residual level of each node based on the residual energy and the average neighbor distance and then the routing protocol is constructed by dynamic adjustment of communication radius.The simulation experiment proves that the improved algorithm can optimize the load balance and achieve the ideal effect.
