Secure data dissemination in MANETs by means of mobile agents

Mobile ad-hoc Networks are dynamic and wireless self-organized networks that many mobile nodes can connect to each other weakly. To compare with traditional networks, they suffer failures that prevent the system from working properly. Nevertheless, in this paper it is coped with many security issues such as unauthorized attempts, security threats and reliability. Using mobile agents in having low level fault tolerant ad-hoc networks provides fault masking that the users never notice. Mobile agent migration among nodes, choosing an alternative path autonomously and, having high level fault tolerance provides more reliable networks, which have low bandwidth and high failure ratio. In this paper, it is declared 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, a new model named as "Secure Mobil Agent Based Fault Tolerance Model" is expressed.
