AN INVESTIGATION STUDY ON ENERGY EFFICIENT AUTHENTICATION TECHNIQUES IN WIRELESS SENSOR NETWORK

Wireless sensor networks (WSNs) are ubiquitous technology for the growth of low cost and low power wireless technology. WSN is the collection of spatially distributed sensors for sensing the physical conditions and organizing the collected data. Sensor nodes have lesser transmission range with limited storage capabilities and energy resources. Routing protocols in WSN guarantee the reliable multi-hop communication from the source node to destination node. An Authentication process is carried out to identify the authorized user for secured routing. In existing authentication methods, key management schemes and hashing techniques were used for increasing the authentication and security level performance. However, the existing techniques failed to improve the authentication accuracy and reduce the authentication time with minimal energy consumption (EC) for secured data transmission in WSN. This paper studied the problem faced using existing authentication techniques in order to increase the security level.
