A Fault-tolerant Scheme for Routing Path Re- establishment for reliable communication in Heterogeneous Networks

In heterogeneous environments, devices accessible in different networks may help to provide new opportunities for utilizing new services when they are connected efficiently. In mobile ad hoc networks, it is very difficult in maintaining the links among the devices, because of the frequent change in the density of mobile devices, their various medium of access nature and their mobility. In this paper, we have considered various aspects of the occurrence of fault in the routing path by predicting in earlier. We have tested the path maintenance procedure using three fault occurring scenarios. Ours is a novel routing scheme named SFUSP (Self-eliminating Fault-tolerant based Un-interrupted reliable Service switching mobile Protocol) which is basically a proactive scheme with added functionalities like clustering and self-elimination. It is specially designed for establishing reliable route in the heterogeneous networks and senses the path link break in advance. Performance evaluation is done for routing metrics and fault-tolerant metrics compared with other protocols like AODV, DSR and OLSR under various mobility models like Random Waypoint, Brownian and Manhattan for different mac layers. Index Terms – Fault-tolerant, Heterogeneous, Self-elimination and Service Discovery. —————————— ——————————
