In Wireless Sensor Networks (WSN), there are multiple types of routing protocols are developed and designed. WSN consists of sensor nodes having energy and storage type capabilities. Sensor nodes are used to transmit the information from the area under observation to the base station, which requires some routing protocols to extend the lifetime of the sensor network. There are multiple techniques available for the routing process in WSN. While using least transmission energy model and less hop routing model techniques, the model generally drains more energy than required, which leads to network and algorithm failure. In this paper, we have used A-Star algorithm to search the optimal path between the source and the destination by extending the network lifetime.in this algorithm, we have used predefined energy of the nodes to participate in to the communication process, the nodes having lower energy then threshold will not participate into the process and tries to find another path.
