Mobile Elements Data Integration and Enhancing Security with Leach Protocol Using WSN

A wireless sensor network is a group of specialized transducers with a communications infrastructure for monitoring and recording conditions at diverse locations. Commonly monitored parameters are temperature, humidity, pressure, wind direction and speed, illumination intensity, vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels and vital body functions. It Provide a bridge between the real physical and virtual worlds. wireless sensor networks was motivated by military applications such as battlefield surveillance; today such networks are used in many industrial and consumer applications, such as industrial process monitoring and control, machine health monitoring, and so on. To enhance the security of sensor nodes, the data transmitted must be encrypted among sensor nodes In this paper we applied Data Encryption Standard scheme to add security to LEACH protocol. The objective of this paper is to add secret encryption scheme to the LEACH protocol.
