Research on Low-energy Multipath Transmission Algorithm in Wireless Sensor Network
In recent years,many research topics have focused on the research of cluster algorithms as a scalable routing proto-col in wireless networks.In these algorithms,by using data aggregation technology and reducing the number of sensors that should be used for long-distance communication,the total energy consumption network life is shortened.Aiming at the problem of limited sensor energy,this paper proposes a new algorithm DECSA,which is an improved algorithm LEACH based on classic clustering.By considering the distance between the nodes and the remaining energy of the nodes,the DECSA algorithm tries to select the appropri-ate node as the CH.In addition,this algorithm aims to generate a multi-level clustering hierarchy,and based on the distance from the CH to the base station,some CHs are selected as the reference station CHs.This paper proposes a clustering algorithm based on DECSA and load balancing.The algorithm combines the minimum and maximum acceptable load thresholds supported by DECSA.Therefore,when the cluster is less than the minimum threshold when it is loaded in a frame,the frame of the cluster is expanded,and when it is greater than the maximum threshold,a part of the cluster load in each frame is transferred to the second CH node.
