Finding the location of an object, other than the sensor in a sensor network is an important problem. There is no good technique available in the literature to find the location of objects. We propose a technique to find the location of objects in a sensor grid. The locations of the sensors are assumed to be known. A sensor can only sense the number of objects present in its neighborhood. This small information injects low traffic in the network. The computations are carried out completely in the base station.
