In recent years Wireless sensor network technology is considered as an emerging
technology where environmental physical conditions are monitored and recorded using
multiple sensors. Central locations are worn for collected data organisation. Multi-hop
communication 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 information
provided by many sensors and gives that entire data’s to base station. Process of collecting
information is done many times because for data efficiency. This method helps to reduce
data transmission energy cost. A basic tree based structured approach is used for this
entire process. To minimize usage of energy and find shortest path between sink and leaf
nodes for data transmission tree-based method is used. Partition Pointed enquiry Region
Routing Algorithm (PPERR) and Partition Enquiry Region Routing (PERR) Algorithm
with LEACH are proposed algorithms. Collection of information and sensing is done in
Protocol called Data aggregation is used in PPERR and in LEACH clustering approach is
worn. Consumption of energy and extension of lifetime are major problems focused here.
NS2 simulation is done for solving these problems.
