Non Uniform Grid Based Cost Minimization and Routing in Wireless Sensor Networks

Recent technological advances have facilitated the widespread use of wireless sensor networks in many applications. In real life situations we have to cover or monitor a lot of points/places on plane. Sensor’s range is proportional to their cost, as high cost sensors have higher ranges. In this paper the authors developed a new algorithm for sensor placement for target location with cost minimization and coverage to non-uniform plane. Sensor placement for target location implies that they are given different type of sensors with different cost and range for given points on plane, which are to be covered with minimum cost. Then the authors discuss how information can be passed from one node to another.
