A Mobile Ad-hoc NETwork (MANET) is a self-configuring network of mobile routers (and associated hosts) connected by wireless links - the union of which form an arbitrary topology. Ad-hoc networks are a new paradigm of wireless communication for mobile hosts. There is no fixed Infrastructure such as base stations for mobile switching. Nodes within each other's radio range communicate directly via wireless links which are far apart rely on other nodes to relay messages. Node mobility causes frequent changes in topology. The wireless nature of communication and lack of any security infrastructure raises several security problems.
