Abstract:
1. A method for cluster based data transmission in wireless sensor networks, comprising: selecting one of a plurality of border nodes positioned at the edge of a cluster as a temporary cluster head based on sensing a target in the cluster; broadcasting data from the one of the plurality of border nodes selected as the temporary cluster head to its own cluster head based at least in part on the selecting bugging data of the temporary cluster head by one or more of the plurality of border nodes in other adjacent clusters to temporarily change the one of the plurality of border nodes selected as the temporary cluster head to a cluster head of each of the one or more border nodes; collecting data from each of the one or more border nodes by the temporary cluster head to transfer the collected data to an actual cluster head of the temporary cluster head; and aggregating the collected data by actual cluster head of the temporary cluster head.
