MANET is a multi-hop temporary communication network of mobile nodes equipped with wireless transmitters and receivers without the aid of any current network infrastructure. MANET is an emerging research area with practical applications. However, MANET is particularly vulnerable due to its fundamental characteristics, such as open medium, dynamic topology, distributed cooperation, and constrained capability. Routing plays an important role in the security of the entire network. Thus operations in MANET introduce some new security problems in addition to the ones already present in fixed networks.
