Fault-Tolerance Mechanism of Mobile Agent In Mobile Ad Hoc Networks

Mobile ad hoc networks (MANET) is a dynamic wireless self-organizing networks. Owing to MANET take the characteristic of dynamic structure and wireless communication, it is much easy to suffer security threats. Fault-tolerance method allow system failure, it make the system continue to calculate effectively in the inaccurate case. Owing to the autonomy peculiarity of mobile agent, nobody natural entity can monitor whole implementing process of mobile agent. Therefore, if there are node or network baulks in system, correlative mobile agent's implement will be prevented. According to the characteristic of ad hoc network and mobile agent, at basis of traditional fault-tolerance techniques, this paper presents a failure-tolerance of mobile mechanism integrating secure authentication technique. It not only assures that the mobile agent can be rightly transmitted but also can avoids the baleful node juggle or destroy the agent, and reduces the time cost of realizing failure-tolerance.
