By arranging the sensor nodes around the target, this article establishes a tracking eluster which can follow the target logically, process data on the target and report to the sink node, thus achieving the tracking function. To improve the security, this article proposes a mobile cluster rekeying protocol （MCRP） to manage the tracking elusterg season key.
