Abstract
Problem statement: The performance of ad hoc routing protocols will si gnificantly degrade when there are faulty nodes in the network. Packet losses and bandwidth degradation are caused due to congestion and thus, time and energy is wasted during its recovery. The fault tolerant congestion aware routing protocol addresses these p roblems by exploring the network redundancy through multipath routing. Approach: In this study, it is proposed to design a fault to lerant congestion aware multi path routing protocol to reduce the rou te breakages and congestion losses. The AOMDV protocol is used as a base for the multipath routin g. This proposed scheme enables more nodes to salvage a dropped packet. Results: Simulation results show that the proposed protocol achieves better throughput and packet delivery ratio with reduced d elay, packet drop and energy. Conclusion: An effective congestion control technique proposed in this study proactively detects node level and link level congestion and performs congestion control us ing the fault-tolerant multiple paths.

Summary
Routing in Mobile Ad-Hoc Network (MANET): A Mobile Ad-Hoc Network (MANET) is a selfconfiguring network of mobile nodes connected by wireless links, to form an arbitrary topology. The sink periodically computes a new reporting rate based on a reliability measurement, the received congestion notification bits and the previous reporting rate fault-tolerant multipath routing protocol has been designed to reduce packet loss due to route breakage. In this protocol, nodes determine multiple disjoint routes using AOMDV (Manjre and Gulhane, 2011) having more battery power and residual energy, to every active destination. Fard et al (2011) have proposed an end-to-end Eav, the average energy of the nodes is given by Eq 2: threshold based algorithm that improves congestion control to address link failure loss in MANET.
