Abstract:

An algorithm based on clustering in WSNs is presented to solve the problem of energy distribution.If the node has enough energy,we use bifurcated approach to select cluster head.Between the cluster heads,the data should be sent through multi-hops to sink.The optimal path for each cluster head is computed by a cost function of energy consumption.In order to further reduce energy consumption,it uses data aggregation in cluster.And experimental results demonstrate that the proposed algorithm prolongs the lifetime of network.
