Secure Routing with AODV Protocol for Mobile Ad Hoc

Mobile Ad Hoc Network (MANET) is a multi-hop wireless network of mobile nodes, forming a temporary network without the aid of any established infrastructure or centralized administration. Due to the absence of any dedicated routers, every node requires to contribute towards the configuration and maintenance of the routing framework. Since there are no centrally administered secure routers, attackers can easily exploit the network. Moreover, open peer-to-peer architecture, shared wireless medium, dynamic topology also adds on to the challenges in the security design of Mobile Ad Hoc Networks. These constrain make traditional secured routing schemes meant for wired networks unsuitable for mobile ad hoc environment. Routing in MANET is a challenging task receiving great amount of attention from researchers. Ad-hoc On-demand Distance Vector (AODV) is one the widely used routing protocols that is currently undergoing extensive research and development. In this paper we present the AODV protocol and survey various security enhancements that have been proposed for AODV by different researchers.
