SECURITY BASED ENERGY EFFICIENT ROUTING PROTOCOL FOR WSN WITH HYBRID OPTIMIZATION TECHNIQUES

Abstract

The use of wireless sensor networks (WSNs) for data collection and transmission through wireless networks has grown significantly. Security is a key design consideration for WSNs since open wireless transmission media are vulnerable to attacks. The security offered by current methods is insufficient because they treat data encryption and routing as two separate problems. So, a novel method called TFEESRP (Trust and Fitness-based Energy Efficient Secured Routing Protocol) is proposed in this paper with the integration of a data encryption phase and a data path selection phase. In the data path selection phase trust and fitness-based optimization techniques like Ant Colony Optimization and Particle Swam optimization (PSO) techniques are used and in the data encryption phase Rivest Shamir Adleman (RSA) security algorithm is used for secured packet transfer through the optimal selected path. The performance of the proposed technique is evaluated in terms of Energy Consumption, End-to-End delay, Packet Delivery Ratio, and Throughput of routing protocol.
