SIBER-DELTAKE: AN IMPROVED ACO-KM-ECC BASED TRUST AWARE ROUTING TECHNIQUE IN WSN WITH OPTIMAL DATA RESOLUTION

摘要

In this paper, our proposed Hybrid model SIBER-DELTAKE, an improved ACO-KM-ECC trust aware routing protocol is presented to provide secure routing in Wireless Sensor Networks by tackling both the identity and behavior related attacks launched by malicious nodes. The proposed SIBER-DELTAKE protocol is built on Ant Colony Optimization (ACO) which employs K-Medoids(KM) algorithm for formation of clusters and setting up of cluster heads to achieve optimal data resolution. It uses Elliptical Curve Cryptography (ECC) mechanism with key generation and management to secure data integrity as well as data privacy thereby establishing secure routing. It further takes into account Distance, Energy, Link Quality, Trust-Awareness metrics in the routing decision to provide trust enabled routing to prevent non-forwarding attacks by insider misbehaving nodes. The performance evaluation of our proposed hybrid model SIBER-DELTAKE was carried-out using NS-2 Simulator for varying network sizes. Our simulation results indicate that SIBER-DELTAKE performs extremely well in terms of malicious node mitigation, delivering of packets, delay in transferring packets, energy consumption and throughput thereby demonstrating the model effectiveness.
