Abstract:

We proposed an algorithm based on double cluster heads clustering and data fusion in wireless sensor network to solve the problems of uneven distribution of clusters and high energy consumption using low energy adaptive clustering hierarchy (LEACH). In the improved protocol, the network uses a clustering algorithm to establish clusters, and then each cluster selects two CHs. One CH is close to sink node and transmits data from its cluster to sink node, and the other CH is close to centroid of the cluster and receives data from general nodes and performs data fusion. Simulation experiments show that the improved protocol reduces the energy consumption of network and extends the lifecycle of network.
