摘要：Mobile Ad hoc NETwork (MANET) is considered as network without infrastructure where communication between the mobile nodes solely depends on the routing protocols which work on assumption that nodes are fully cooperative. In the presence of malfunctioning nodes, most of the routing protocols show dropped performance and in some case whole of the network fails. Malfunctioning nodes interrupt the data flow by either by dropping or refusing to forward the data packets thus forcing routing protocol to restart the route-discovery or to select an alternative route if available which may again include some malfunctioning nodes, thereby forming a loop, enforcing source node to conclude that data cannot be further transferred. In this paper, a new reputation based approach is proposed which deals with such malfunctioning nodes and can be integrated on top of any source routing protocol Proposed approach consists of detection and isolation of misbehaving nodes and based on sending acknowledgement packets back for reception of data packets.
