ABSTRACT

To construct a reliable mobile adhoc network one of the important design issue is Faulttolerance. Due to the link failure, node failure, misbehaving nodes, network failure, power and energy consumption many types of faults may occur in mobile network. Numerous existing designs of ad hoc networks are based on the idea of non-adversarial environments, in which each node in the network is supportive and well-mannered. Several fuzzy logic based shortest route selection algorithms are developed but they failed to handle the contradiction rules are generated by inference system. It results in selection of incorrect path selection, which doesn’t able to handle the fault occurrence. The proposed work has the ability to accept the contradiction occurred among the generated rules for path selection and it treats them as a special case with the help of multi-valued logic termed as paraconsistent logic which contributes for selection of shortest route in case of faults.
