Abstract

Mobile ad hoc networks (MANETs) are a setup of several independent nodes that are capable of transmitting any kind of data by themselves. In MANETs, the node themselves act as routers and the setup can either be single hop or multihop depending on the application. These devices have wide and varied applications; like in military deployment, for network set up in meetings, electronic classrooms etc. As the applications and use of MANETs has increased, it has also become imminent for MANETs to support multimedia transmission, high quality data transmission and also to work efficiently in a congestion scenario. To support these parameters it is necessary to have a robust routing protocol that provides good Quality of Service (QoS) parameters under different conditions. In this paper the authors simulate transmission of multimedia traffic with AODV nthBR routing protocol for a high density MANET setup. AODV nthBR routing protocol is also simulated for a congestion scenario and the results are then compared with the existing routing protocols.

Abstract

Objectives: In this paper, a backup routing solution in which routes are selected based on their energy efficiency is presented. Methods: The selection of nodes is based on energy efficiency. Nodes that are nearest to the failed node are found out and checked for their energy efficiency. Depending on whether nodes are energy efficient or not, they are classified as alive or dead. The selected node is then used for data transmission to the destination. Backup routing is done with the help of alive or energy efficient nodes. These nodes are first chosen based on how close they are from the failed node and then the energy available with them is checked. It is shown through experimental results that the obtained QoS parameters are better than the traditional routing protocols. Findings: It is found that after 6000 rounds of transmission, in a MANET of size 100 nodes, throughput obtained with energy efficient AODV BR protocol is 107800 bits. Also, PDF obtained is 0.187 and end to end delay is 0.05422 secs after 6000 rounds. Applications: MANETs find use in education purpose like e-classrooms, in war zones, in disaster affected areas or even in places where the cost of establishing a setup needs to be minimized. MANETs have diverse applications such as in warfare, earthquake or disaster stricken areas etc. and require good Quality of Service (QoS) parameters. The existing work provides QoS parameters when the link is not broken. However it is desirable to provide a system that continues to provide good QoS parameters even when the existing link fails. In this paper efforts have been made to provide for such a system that searches for an alternate link on failure of the main route based on certain energy efficiency criteria such that the network provides good QoS parameters in various applications.
