Abstract: A target following clustering algorithm of the present invention generates or eliminates a cluster dependently following a target when detecting the target in surveillance reconnaissance applications, thereby sensitively responding to motions of the target even when traffic of a wireless sensor network bursts locally by the detected target. Also, it is possible to improve energy efficiency since both a boundary problem and a blackhole can be resolved. Moreover, the target following clustering algorithm reduces costs of system maintenance in the military with weak electricity infrastructures and has high applicability by reducing energy consumption in the wireless sensor network and prolonging the lifetime, namely, duration time of the network.
