A zone adaptive distance and failure analysis approach for reliable target tracking

A sensor network is defined with normal nodes and critical target nodes. To improve the network lifetime it is required to monitor these target nodes effectively. In traditional algorithm distance analysis based approach is used for target acceptability. In this paper, a zone adaptive distance approach is defined to identify the cover node to track the target. The work is defined in three main stages. In first stage, the zone distance, energy and fault based analysis is performed to identify the cover nodes. In second stages, the cover fault analysis based approach is used to identify the coverset. In third stage, the energy and fault adaptive coverset activation sequence is defined so that effective target tracking will be obtained. The presented work is implemented in matlab environment. The result shows the significant improvement in network life.
