低功耗有损网络中的能量均衡高效路由协议
Energy-balanced and High-efficiency Routing Protocol for Low-power and Lossy Networks
摘要
Abstract
In existing Routing Protocol for Low-power and Lossy Networks (RPL ) which selects the best parent according to expected lifetime of bottleneck node on the path,the joining nodes do not consider the traffic generated by the other sub-nodes of the same parent node or the change of bottleneck node after the node’s joining.Aiming at these problems,this paper presents an Energy-balanced and High-efficiency RPL(EBHE-RPL).Firstly,it uses a classifying sending mechanism for DAO-ACK messages to reduce the number of control packets sent by the parent node.Secondly, it uses a traffic accumulation mechanism to calculate the Expected Life Time(ELT)of bottleneck node on each path,so that the calculated life time is closer to the actual value.Finally,it uses a bottleneck re-estimating mechanism after node’ s joining to avoid the bottleneck’s change.EBHE-RPL can improve the accuracy for selecting the best parentand balance the energy of networks.Simulation results show that,compared with RPL and EB-RPL algorithms,the performance of EBHE-RPL is improved in the extension of network lifetime and the balance of network energy.关键词
