An Improved Quality of Service Using R-AODV Protocol in MANETs

Abstract

Mobile ad hoc Networks (MANETs) is a type of wireless ad hoc network which is a self-arranging network of mobile nodes connected by wireless links that create a discretionary topology. The mobile nodes are free to move randomly and to arrange themselves in a random manner. Thus, the wireless ad hoc network topology may expand rapidly and unpredictably. In Mobile ad hoc networks, the routing protocol plays an important role for improving Quality of Service (QoS). There are many different types of routing protocols such as reactive, proactive, and hybrid. In reactive routing protocol, AODV is a one which establishes routes on-demand, as they are needed. In this paper, we proposed a new routing protocol called Reverse Ad hoc On-Demand Distance Vector (R-AODV) routing which reduces route path fail correction messages and gives better performance than the original AODV routing protocol with respect to set of performance metric such as packet delivery ratio, throughput, energy consumption, and overhead under different pause time. We designed the R-AODV routing protocol and implemented with certain simulation parameters using Network Simulator (NS-2) tool. The performance analysis of routing protocol designed for wireless networks has been very challenging. Hence, simulations are always utilized to obtain the desired performance results.
