Abstract

In a mobile ad hoc network (MANET), groups of mobile devices band together for a limited time to create a network that does not require any permanent infrastructure. Its use stems from the fact that it requires nothing in the way of upkeep or organization and can be moved from place to place thanks to wireless connections. The first is a decrease in network performance, and the second is a lack of security. Multiple attacks have hampered the efficiency of mobile ad hoc systems. For the sake of this article, we have limited our attention to network-layer active attacks. As a reactive routing system for ad hoc networks, Ad Hoc On-Demand Vector Routing protocol simply keeps routes between communicating nodes. AODV ensures that there are no routing loops even if a connection fails. Safe Ad-Hoc On-Demand Routers (SAODV) provides a trustworthy routing system for mobile ad-hoc networks. Our approach employs SAODV protocol and the Hybrid Cryptography Technique (DES, RSA Algorithms) on SAODV to boost performance and ensure confidentiality in MANET. This study provides a simulation-based comparison of the MANET routing protocols AODV and SAODV across a range of performance, energy, and packet-delivery metrics. The NS2 network simulation environment is used to realize the suggested cryptographic routing algorithm. As a result of implementing our proposed strategy, we see reduced energy consumption, a high packet delivery ratio, and a high throughput.
