Node authentication and encrypted data transmission in mobile ad hoc network using the swarm intelligence-based secure ad-hoc on-demand distance vector algorithm

Abstract

In a mobile ad hoc network (MANET), all nodes are communicated with one another across wireless networks to create a temporary network without the support of centralised management. Due to dynamic topology in MANET, secure routing is a crucial issue. The existing secure routing protocol and their security concerns are analysed in this work. The suggested Swarm Intelligence-based Secure Ad-hoc On-demand Distance Vector (SIS-AODV) algorithm offers security by applying a secret key and hash mechanism to prevent the involvement of malicious nodes in routing operations. A secure routing system of MANET guards against internal and external network attacks. The proposed SIS-AODV algorithm consists of two sections: the secret key value generated by applying Elliptical Curve Cryptography (ECC)-based algorithm and the PRESENT algorithm to encrypt the data packets. Besides, authentication and non-repudiation are applied using the H-PRESENT 128 algorithm. The PRESENT algorithm and H-PRESENT 128 hash function require less computational power. Centralised management is optional in this scheme, so overhead decreases. The second section of SIS-AODV consists of Ant Colony Grey Wolf Optimization over the AODV algorithm to improve network performance while implementing a security algorithm over MANET. Analysis results show maximum performance with a packet delivery ratio of 98% and throughput of 85%. In addition, end-to-end delay is reduced by up to 25%, and routing overhead decreases by up to 20%.
