In recent years Wireless sensor network technology is considered as an emergingtechnology where environmental physical conditions are monitored and recorded usingmultiple sensors. Central locations are worn for collected data organisation. Multi-hopcommunication is used to transmit data to sink node. To remove unwanted transmission,best known WSN method called Data aggregation is used. Its job is to collect informationprovided by many sensors and gives that entire data’s to base station. Process of collectinginformation is done many times because for data efficiency. This method helps to reducedata transmission energy cost. A basic tree based structured approach is used for thisentire process. To minimize usage of energy and find shortest path between sink and leafnodes for data transmission tree-based method is used. Partition Pointed enquiry RegionRouting Algorithm (PPERR) and Partition Enquiry Region Routing (PERR) Algorithmwith LEACH are proposed algorithms. Collection of information and sensing is done inProtocol called Data aggregation is used in PPERR and in LEACH clustering approach isworn. Consumption of energy and extension of lifetime are major problems focused here.NS2 simulation is done for solving these problems.
