A Mobile Ad-hoc NETwork (MANET) is an autonomous network. It is a collection of mobile nodes that communicate with each other over wireless links. From last few years, the interest in the area of Mobile Ad-hoc NETwork (MANET) is growing due to its practical applications and requirement of communication in mobile devices. In the comparison to wired or infrastructure-based wireless network, MANET is vulnerable to security attacks due to its fundamental characteristics, e.g., the open medium, dynamic network topology, lack of clear lines of defense, autonomous terminal, lack of centralized monitoring and management.
