“…Regarding fault tolerance in MANETs, Nsaif et al [33] introduced an approach referred to as seamless routing for wireless ad hoc networks (SRAD). Here, each pair of nodes had two link-disjointed paths, which were used to transmit two redundant frame copies to the destination such that zero-recovery time was achieved in the case where one of the operating paths fails.…”

Fault-Tolerant Ad Hoc On-Demand Routing Protocol for Mobile Ad Hoc Networks

Mobile ad hoc networks (MANETs) are particularly suited for scenarios that demand rapid deployment of a communication system without any existing network resources. For instance, a MANET can facilitate the intercommunication process between members of a rescue party in a natural disaster, where the underlying routing protocol is crucial to maintaining the dissemination capability of data-critical packets. However, the backbone of every MANET, i.e., their routing protocol, is limited by the communication range of nodes, their high-speed mobility, and the capacity constraints of energy. This study proposed a fault-tolerant ad hoc on-demand routing protocol (FT-AORP) that relies on these characteristics of MANET nodes to determine reliable paths for data transmission. Subsequently, two of the discovered paths were used to transmit the duplicates of an original data packet to maximize fault tolerance. Further, using the OMNeT++ network simulator, the performance of the proposed system was evaluated through extensive simulation experiments against three simulation parameters: the number of network nodes, node speed, and data packet sending rate. The simulation results demonstrated that FT-AORP greatly improved the packet delivery ratio, reduced end-to-end delay, and maintained a higher residual energy level of the transmission path, compared to other baseline routing protocols.INDEX TERMS Mobile ad hoc network, fault tolerance, network mobility, on-demand routing protocol.
