Sensors are tiny devices and senses different types of inforamation. The sensing range of each sensor is limited due to its energy holding capability. Active participation of sensors in data transmission to base station minimizes the overall energy consumption and also reduces the overall systems cost. In this regard division of the total sensor field wiht uniform grids is the best solution. Leveling is the technique to divide the entire sensor field in to different layers. Cluster head collects the information from various sensors with in the lavel and uniform grid and also sends the inforation towards Base station with minimized routing with proper hopping and living techniques. Cluster Head plays an important role in data transmission with the helpf of sources nodes and router nodes. Here we are proposing two different types of base statation position placements. One is base station at the middle of the uniform grid and second one is at rightmost corner. Using these concepts we are reducing the power consumption of the sensor field.

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.
