Aggregation tree constructing algorithm based on clustering for sensor networks

An aggregation tree constructing algorithm based on clustering is proposed,according to the limited resources of nodes in Wireless Sensor Network(sWSNs).The proposed algorithm uses clustering's hierarchical structure to decrease routing control overhead and improve the networks scalability,and uses data aggregation tree to deal with redundant information and reduce traffic. The simulation results show that the proposed algorithm can reduce energy consumption efficiently and prolong networks lifetime. The pe...
