In wireless sensor networks, all the sensors are deployed at untrustworthy environments and base station is far away from the sensors. To increase the lifetime of the sensor network entire region is divided into clusters. The sensors in the cluster have been communicated thorough the cluster heads. All the sensor in the network are busy in sensing, transmission of the messages, due to this any sensor will gone into dead state which causes delay in data transmission. This affects the traffic overload in other paths. To overcome this problem we are proposing an energy aware factor based location security algorithm which transmits the messages in a route which is selected based on reliability and energy levels of the different routes. The proposed methodology also includes homorphic energy-based encryption encrypts the data related to the sensor node with less computational complexity. Heuristic conditions are used for optimizing the sampling rate and battery level for tackling the battery capacity constraints of the wireless sensor nodes.
