A Mobile Ad hoc NETwork (MANET) is a self-governing network comprised of free roaming nodes which communicate wireless by radio transmission. As MANET edge closer toward wide-spread deployment, security issues have become a central concern and are increasingly important. Various security mechanisms have been proposed, widely used, and proven to be effective in wired networks, but no single mechanism provides all the services required in a MANET. Due to certain characteristics of MANETs, some security mechanisms are not applicable to this environment.
