A dynamic tracking mechanism for mobile targets in cluster-based WSNS

摘要

How to save energy for target tracking in WSNs is an important issue. The basic idea of energy-saving method is using sleep mechanism to make nodes into sleeping until they are awaking to process target sensing scheme. However, if nodes enter sleep state too much, targets may lose easily from the sleeping nodes. It is high consuming the energy to find back these losing targets. Thus, it would notice accuracy of tracing targets when saving energy. In this proposal, it offers a scheme about trace of moving target. It uses cluster scheme and algorithm, which apply different strengths and energy-consuming according to different possibility of losing targets. The possibility of lost is aimed to different acceleration of targets and wake up different number of nodes. Lowering losing rate of target can own energy-saving and improved performance.
