Enhanced Ad-Hoc on Demand Multipath Distance Vector Routing protocol

TL;DR

This paper introduces EAOMDV, an enhanced routing protocol for mobile ad-hoc networks that predicts link failures using signal power to improve route stability, reduce delays, and increase throughput.

Contribution

The paper proposes EAOMDV, a novel extension of AOMDV that preemptively predicts link failures to enhance routing performance in mobile ad-hoc networks.

Findings

EAOMDV reduces route failures compared to AOMDV.

EAOMDV decreases network delay and overhead.

EAOMDV improves throughput in NS-2 simulations.

Abstract

Due to mobility in Ad-Hoc network the topology of the network may change randomly, rapidly and unexpectedly, because of these aspects, the routes in the network often disappear and new to arise. To avoid frequent route discovery and route failure EAOMDV was proposed based on existing routing protocol AOMDV. The EAOMDV (Enhanced Ad-Hoc on Demand Multipath Distance Vector) Routing protocol was proposed to solve the "route failure" problem in AOMDV. EAOMDV protocol reduces the route failure problem by preemptively predicting the link failure by the signal power received by the receiver (pr). This proposed protocol controls overhead, increases throughput and reduces the delay. The EAOMDV protocol was implemented on NS-2 and evaluation results show that the EAOMDV outperformed AOMDV.
