With the constant technological advancements, the era of wired networks are on a decline and the wireless network is overpowering its traditional counterpart. In recent years Mobile Ad hoc NETworks (MANETs) have become a very popular. Providing communications in the absence of a fixed infra-structure MANETs are an attractive technology. MANET is particularly vulnerable due to its fundamental characteristics, such as open medium, dynamic topology and distributed cooperation. However, this flexibility introduces new security risks. Threats exist to a mobile ad hoc network both from external nodes unauthorized to participate in the mobile ad hoc networks, and from internal nodes, which have the authorization credentials to participate in the mobile ad hoc network.
