Mobile Ad-hoc NETworks (MANETs) are self-configuring networks that designing an efficient routing is one of the most important challenging issues of them due to nodes mobility and wireless communications. Frequently changing topology and high fault and failure probability in MANETs lead to perform frequent routing procedures and consequently cause considerable overhead on the network resources. Therefore, using a fault tolerant protocol that can find routes with high reliability is essential for reducing routing overhead and improving performance. In this paper, the authors present a multipath routing protocol based on well known AOMDV protocol. Presented protocol computes a reliability value for each node in the network using connectivity level between nodes and activity level of each node, dynamically.
