Energy Efficient Target Tracking Mechanism using Rotational Camera Sensor in WMSN

Wireless Multimedia Sensor Networks (WMSN) have recently gained the attention of the research community due to their wide range of applications like Multimedia Surveillance Sensor Network, Environment monitoring and the advancement of Complementary Metal Oxide Semiconductor (CMOS) cameras. Energy-efficient operations are particularly important in order to extend monitoring over a long period of time. In this paper an energy efficient mechanism Energy Efficient Target Tracking (EETT) is presented in which the target detection capability is increased by means of rotation of camera sensor node in WMSN as it detects any target in its Field of View (FoV) and rotates until the target moves out of CS's FoV. On an average 50.7704% energy efficiency is achieved in EETT.
