EIGRP-Based Hybrid Routing Approach for MANETs

---

Abstract

In a MANET (mobile ad-hoc network), several mobile nodes are wirelessly linked to each other, but there is no central network infrastructure. The topological changes that occur often, the efficient use of the energy resources that are available, the associated routing overheads, and susceptibility to assaults are the main challenges encountered in the design of routing protocols for MANETs. This article presents a more secure and efficient routing method that makes use of modified EAACK when used with hybrid EIGRP. EIGRP uses the DUAL, an enhanced distance vector protocol, to establish the optimal route between source and destination. Using the modified EAACK scheme, this method successfully addresses several of the shortcomings of standard intrusion detection systems. S-ACK is unable to tell the difference between a legitimate node and a malicious one. When looking for malicious nodes, P2P ACK is superior to S-ACK. In this technique, the P2P ACK acknowledgment packets of the modified EAACK are signed and verified using the RSA algorithm. To improve MANET security, the suggested approach makes use of a modified version of the RSA public key cryptography technology. This suggested method improves overall performance by raising security standards, cutting down on routing overhead, and speeding up packet deliver
