Paper Title
Digital Signature Approach For Energy Efficient Protocol Using Gateway Nodes In WSN

Wireless Sensor Network contains many heterogeneous or homogeneous tiny sensor devices with limited power resource. The main objective of this sensing device is to collect or gather information from the human unreachable area and deliver the data to the nearest base station. Such devices contain three main components: a sensor, a processor, a wireless communication device. The main focusing area of these devices is to maintain their energy as well as providing security to ensure communication between two nodes. Knowing that the sensor power source is not replaceable, many protocols have been introduced to provide efficient way to sustain the energy. But most of the existing energy efficient protocols like LEACH, PEGASIS does not concentrate on efficient load balancing. Our paper is about the energy efficient protocol that offers a better performance both in single hop and multi hop routing even in case of overloading in clusters. We also concentrated on security by using digital signature algorithm providing authentication between sources considering both in terms of sensors life and energy consumption.
