Target Tracking Based on Connected Dominating Set in WSN

Target tracking application in WSN should solve the problem of target status sharing well. To overcome the shortages of DCTC and cluster-based method, method using connected dominating set based aggregation tree is introduced. According to whether node has the capability of locating, target status information can be shared in aggregation tree by broadcast or unicast. Because of the structure stability of aggregation tree, target can be continuously monitored while it shift between different coverage area of sensors. The target status reaches base station after step by step data fusion in the aggregation tree, which will greatly reduce redundant packets to save node energy.
