Mobile Ad-Hoc Networks are dynamic and wireless self-organization networks that many mobile nodes connect to each other weakly. To compare with traditional networks, they suffer failures that prevent the system from working properly. Nevertheless, we have to cope with many security issues such as unauthorized attempts, security threats and reliability. Using mobile agents in having low level fault tolerance ad-hoc networks provides fault masking that the users never notice. Mobile agent migration among nodes, choosing an alternative paths autonomous and, having high level fault tolerance provide networks that have low bandwidth and high failure ratio, more reliable. In this paper we declare that mobile agents fault tolerance peculiarity and existing fault tolerance method based on mobile agents. Also in ad-hoc networks that need security precautions behind fault tolerance, we express the new model: Secure Mobil Agent Based Fault Tolerance Model.
