Study and Analysis of Network based Intrusion Detection System

Abstract: Mobile means random and perhaps constantly changing or moving and ad-hoc means for this or temporary without any centralized administration. Mobile ad-hoc network is a collection of mobile nodes forming an instant network characterized by wireless links, dynamic topology and easy deployment. The wireless links in this network are highly prone to error. Routing is a challenging task for networks that do not offer fixed infrastructure, like in ad-hoc wireless networks that offer unrestricted mobility. Based on Routing Update Mechanism, there are two broad categories of Routing Protocol viz. Table- Driven Routing Protocols includes; protocols like DSDV & WRP and On-Demand Routing Protocols include protocols like DSR, AODV & LMR. In this paper, an attempt has been made to analyze three well known protocols namely, DSR, AODV and DSDV.
