Data aggregation in wireless sensor networks eliminates redundancy to improve bandwidth utilization and energy efficiency of sensor nodes. One node, called the cluster leader, collects data from surrounding nodes and then sends the summarized Information to upstream nodes. This algorithm used to select a cluster leader that will perform data aggregation in a partially connected sensor network. The algorithm reduces the traffic flow inside the network by adaptively selecting the shortest route for packet routing to the cluster leader. It is assumed that an Eavesdropping Fusion Center (EFC) attempts to intercept the transmissions of the sensors and to detect the state of nature.
