In many applications, sensors can be precisely placed to optimally achieve their intended monitoring function. However circumstances arise in which sensors must be delivered to a remote location by air drop or from gun launched projectiles due to presence of hostile forces and environments or unavailability of resources for their accurate placement. Consequently, sensors are distributed in a random pattern. This paper presents an approach to locating each sensor in the net from a remote location. It further describes an approach to propagating the coordinates to a remote control point and identifying the coordinates of sensors activated by intrusion.
