Enhancing Security in MANET through EAACK: A Novel Approach for Node Detection, Acknowledgment Validation and Routing Optimization

This research proposal introduces EAACK (Enhanced Adaptive Acknowledgement), a novel approach with the primary objective of enhancing security within Mobile Ad hoc Networks (MANETs). The inherent security challenges faced by MANETs, including the presence of misbehavior nodes and the occurrence of fabricated acknowledgments, have considerable consequences for both data integrity and the overall efficiency of the network. EAACK takes a proactive stance by leveraging a Peer-to-Peer (P2P) ACK mechanism to swiftly address misbehavior nodes, and it further fortifies data transmission security through the seamless integration of RSA-based encryption techniques. EAACK's efficacy is particularly evident in its successful integration with the EIGRP hybrid protocol, leading to optimization of routing processes and a consequential reduction in overhead. The performance of EAACK is meticulously evaluated through simulations conducted using Network Simulator 2 (NS2), involving a comprehensive comparison with established methods such as TWOACK and Watchdog. The outcome of these simulations underscores EAACK's superiority, boasting higher Packet Delivery Ratio, lower Routing Overhead, and minimized Time Delay. In essence, EAACK transcends its role as a mere security solution; it emerges as a multifaceted network optimizer. By effectively targeting vulnerabilities and harmonizing the intricate aspects of node detection, acknowledgment validation, and routing optimization, EAACK positions itself as a pivotal contributor to establishing a secure and resilient ecosystem for MANETs.
