A Comprehensive Study on Energy-Efficient and Secure Communication Strategies in WSN

Abstract

Wireless Sensor Networks (WSNs) are group of sensor nodes (SN) distributed in space and linked through wireless communication. WSN include the processors, battery modules and wireless communication devices. SN gathers and transmits the environmental information to BS for efficient processing. WSN includes low-power and low-cost devices for administration because of critical roles of energy as well as security. SN is dependent on batteries that experienced the energy loss with minimum network lifetime. Consequently, energy efficient data broadcast is performed in WSN through optimization methods. Dissimilar researchers performed their research on energy efficient and secured information broadcast by optimization and cryptographic methods in WSN. However, energy consumption was not minimized and data confidentiality rate was not enhanced by existing techniques. The main aim of research work is to reduce energy utilization and increase the network security using cryptographic and optimization techniques.
