Abstract: Ad-hoc networks are an emerging area of mobile computing. There are various challenges that are faced in the Ad-hoc environment. In this paper we attempt to analyze the demands of Ad-hoc environment. We focus on three areas of Ad-hoc networks, key exchange and management, Ad-hoc routing, and intrusion detection. The key issues concerning these areas have been addressed here. We have tried to compile solutions to these problems that have been active areas of research.
