An Empirical Study of UDP (CBR) Packet Performance over AODV Single & Multi-Channel Parallel Transmission in MANET

TL;DR

This paper empirically compares UDP (CBR) packet performance over AODV routing in single and multi-channel MANET environments using NS2, analyzing QoS metrics to evaluate protocol efficiency.

Contribution

It provides an empirical analysis of AODV performance in single and multi-channel MANETs, highlighting potential improvements with Parallel MAC (P-MAC).

Findings

Multi-channel environment improves throughput and reduces delay.

Parallel MAC (P-MAC) can enhance multi-channel performance.

AODV performs differently under various QoS metrics in different environments.

Abstract

Mobile Ad-hoc Network is a temporary network which is the cooperative engagement of a collection of standalone mobile nodes that are not connected to any external network. It is a decentralized network where mobile nodes can be easily deployed in almost any environment without sophisticated infrastructure support. An empirical study has been done for AODV routing protocol under single channel and multi channel environment using the tool NS2. To compare the performance of AODV in the two environments, the simulation results have been analyzed by graphical manner and trace file based on QoS metrics such as throughput, packet drop, delay and jitter. The simulation result analysis verifies the AODV routing protocol performances for single channel and multi channel. After the analysis of the simulation scenario we suggest that use of Parallel MAC (P-MAC) may enhance the performance for multi channel.
