Using an Improved Hormone Secreting Mechanism to Realize Persistent Object Tracking in WSN

Target tracking with the wireless sensor networks (WSN) has been an issue full of potentialities and challenges. In this paper, an improved hormone secreting mechanism for object tracking based on the information exchange principle of the endocrine system of human body is proposed. The nodes in a completely decentralized network can tune themselves spontaneously by exchanging information about the environment with their regional neighbors. Comparative simulation shows that proposed strategy can perform independently without the aid of other auxiliary algorithms for maintain the network status. The tracking mission towards the invading object can also be conducted more efficiently and persistently, and the energy consumption can therefore be distributed to the whole network.
