Abstract

This talk describes one of the major efforts in the sensor network community to build an integrated sensor network system for energy efficient surveillance. The focus of this effort is to acquire and verify information about enemy capabilities and positions of hostile targets. Such missions often involve a high element of risk for human personnel and require a high degree of stealthiness. Hence, the ability to deploy unmanned surveillance missions, by using wireless sensor networks, is of great practical importance for the military. Because of the energy constraints of sensor devices, such systems necessitate an integrated energy-aware design to ensure the longevity of surveillance missions. In this talk, we describe the design and implementation of an integrated running system, called VigilNet, for energy-efficient surveillance. The VigilNet allows a group of cooperating sensor devices to detect and track the positions of moving vehicles/personnels in an energy-efficient, responsive, robust and stealthy manner. VigilNet integrates over 30 protocols and consists about 40,000 lines of NesC and Java code, running on XSM, Mica2 and Mica2dot platforms. It has been recently successfully transferred and classified for realistic military deployment.
