MODIFIED FLEXIBLE NODE AUTHENTICATION FOR MANETS: HASH CHALLENGE–RESPONSE FOR SECURE DYNAMIC SOURCE ROUTING (DSR)

Mobile Ad Hoc Networks (MANETs) are a novel technology that has a dynamic topology, self-configuring, and self-motivated. The primary feature of an ad hoc network isn’t dependent on any established infrastructure because it lacks a centralized arbiter or server. Wireless MANETs have several issues, including performance analysis, energy efficiency, security, and network stability. To date, a great deal of research has been conducted to create security strategies for MANETs. The current strategies that aim to build a defense against different types of attacks at different levels will be covered in this analysis. Researchers therefore create several routing protocols. Wireless networks cannot effectively employ the routing methods designed for conventional networks. A few novel routing methods have been developed for wireless ad hoc networks that are appropriate for the constantly evolving ad hoc wireless environment. In this study, we proposed a technique to improve the efficiency of routing protocols and boost node-to-node dependability in mobile ad hoc networks (MANETs). Our system focuses on node authentication, and we use an on-demand routing protocol, such as the Dynamic Source Routing protocol (DSR), to implement it. This technique relies on the hash function, secret value, and time stamp.
