A Wireless Sensor Network (WSN) is composed of sensor nodes which are randomly distributed over the network. In this dissertation, a network is taken in which nodes are randomly deployed in (100100) m2 area for collecting and aggregating data and transmit it to base station (i.e. sink node). For this purpose in proposed work nodes are arranging in hierarchy by using suitable algorithms and partitioning of network into 3 areas (named tiers). After that a head is chosen among all nodes based on their distance from base station.
