Abstract

Objectives: Security is a challenging issue in mobile ad-hoc networks (MANET). The main objective is to implement FD-ETOHIP Fault Detection Mechanism (FDM) on Enhanced Topology-Hiding Multipath Routing Protocol (E-TOHIP) in mobile ad-hoc networks (MANETs). Methods/Statistical Analysis: E-TOHIP do not permit packets to hold routing information. Once a route is recognized, E-TOHIP will publicize a set having the nodes that have been positioned on routes, which prevents a node from being located on another route. It also establishes multiple node-disjoint routes and excludes unreliable routes before transmitting packets. Findings: With the help of FDM faults in the network can be easily identified. Message loss due to node permanent fault and message loss due to data transmission are the types of faults that occur here. If the node is considered to be a everlasting fault, then the messages at the node location will get lost and it won’t work until a re-establishment is done. The message loss during data transmission occurs due to three kinds of faults namely message redirection, topology change and buffer overflow. Applications/Improvements: Along with FDM, various attack implementation is also done in order to test the efficiency of E-TOHIP protocol.
