The Ad hoc networks can be developed, merged or separated into different networks instantaneously without necessarily relying on a solid infrastructure for energy management. The nodes of AdΗoc mobile networks are often indicating that applying wireless communication to maintain the connection and the specific type of these networks is called Mobile AdHoc Networks (MANET). Regarding attacks on Manets physical layer of OSI model is increased because of the status of these wireless networks which have the means of transmission in the air. The MANET based on open "peer to peer" architecture multihops to make contact at the network level. The attacks may also be made at the data link disrupting cooperation protocols at that level. The basic idea behind the attacks at the network layer is to absorb network traffic and cause a diversion and thereby control the flow of network traffic. The objectives of the protocol TCP (transport layer protocol) to Manet include the establishment of a «end-to-end» link, association of «end-to-end» reliable delivery of packets, flow control, congestion control and offset the «end-to-end» link at the end. The attacks on application level is attractive to attackers because information seekers are in their applications and this has an impact on achieving their goals. Some of the attacks on Manet can start and run more than one level of the OSI model. The success of Manet networks depends largely on whether safety standards are trusted. However, the characteristics of Manets create challenges and opportunities for the achievement of security such as confidentiality, authentication, integrity, availability, access control and non-repudiation.
