An optimized multipath routing for secure communication of wireless sensor network

Abstract

Energy efficiency is the prime concern in Wireless Sensor Network because of the limitations on the power source for the sensor nodes. The proper routing technique can greatly contribute in energy consumption and efficient power dissipation in WSNs. Also the packet loss is major problem in the communication process. This paper emphases on energy conservation and secure data communication in a wireless sensor network using multipath routing technique public and private key cryptography. The optimized multipath routing technique deals the aspect to improve security, reliable transmission of data and power consumption. This paper concentrates on securing the data transmission with energy efficient routing. In this technique communication between nodes is setup in three phase path finding, data transmission and path maintenance with data security. For securing the communication this technique uses public cryptography which is initiated by the source node. This authentication and authorization secures the packets and minimizes the packet loss during the communication. The implementation results shows the improved energy consumption and maximizes the packet delivery ratio with minimizing the packet loss.
