Ad hoc networks are a new-fangled wireless networking paradigm for mobile nodes. Unlike traditional wireless networks, ad-hoc networks do not rely on any fixed infrastructure. Instead, the mobile nodes rely on each other to share the information. The main dispute in designing these networks is their susceptibility to security attacks. The increase in number of applications of ad-hoc networks depends on a large number of factors, with reliability being one of the key challenges to be met. Ad-hoc On-demand Distance Vector (AODV) is one of the extensively used protocols which do not satisfy the various security requirements like availability, confidentiality and integrity. This paper discusses the various security requirements for the ad-hoc networks and the various security enhancements of AODV protocol.
