چکیده
The advances in sensing devices and integrated circuit technology have allowed for the development of easily \re-conngurable smart sensor" products. Primarily utilizing commercial oo-the-shelf (COTS) components, we have developed reconngurable smart sensors, consisting of a microprocessor, GPS receiver, RF transceiver, and sensor. The standard serial control interface allows for ease of interchangeability for upgrades in RF transmission schemes as well as customizing the sensing device (i.e. temperature, video images, IR, motion, Ethernet) per application. The result is a exible module capable of gathering sensor data, local processing, and forwarding compressed information to a central location via other modules. In this paper, we present our system infrastructure design and a cost function based geographical self-routing algorithm for networking reconngurable smart sensors. The algorithm allows for the sensors to automatically negotiate in a geographical radial topology relative to a central location, utilizing other sensors as routes or hops for forwarding information to a this central location. A number of these sensors are deployed in the eld and performance measurements for routing times are analyzed and presented.
