Abstract: In order to reduce the energy consumption in wireless sensor networks, a clustering algorithm based on aggregation degree and weighted function timing for wireless sensor networks is proposed. The algorithm elects the proper cluster headers by different duration of timing based on the weighted function with the aggregation degree and residual energy as its two parameters. Without comparing the aggregation degree of each node, the communication overhead is greatly reduced. As a result, the energy consumption is reduced. Simulation results show that the proposed clustering algorithm is convergent with steady scale of cluster headers and effectively extends the network lifetime.
