QoS Routing and Performance Evaluation for Mobile Ad Hoc Networks using OLSR Protocol
Mohamed Amnai, Youssef Fakhri, Jaafar Abouchabaka

TL;DR
This paper evaluates the performance of the OLSR routing protocol in mobile ad hoc networks under different mobility models and traffic types, highlighting how mobility and traffic influence key performance metrics.
Contribution
It provides a comparative analysis of OLSR performance with real-time VBR and CBR traffic across various mobility models, which is a novel evaluation approach.
Findings
OLSR performance varies with mobility models and traffic types.
Mobility and traffic significantly impact end-to-end delay, throughput, and packet delivery ratio.
Real-time VBR traffic affects OLSR differently than CBR traffic.
Abstract
Mobile Ad-Hoc network is a collection of mobile nodes in communication without using infrastructure. As the real-time applications used in today's wireless network grow, we need some schemes to provide more suitable service for them. We know that most of actual schemes do not perform well on traffic which is not strictly CBR. Therefore, in this paper we have studied the impact, respectively, of mobility models and the density of nodes on the performances (End-to-End Delay, Throughput and Packet Delivery ratio) of routing protocol (Optimized Link State Routing) OLSR by using in the first a real-time VBR (MPEG-4) and secondly the Constant Bit Rate (CBR) traffic. Finally we compare the performance on both cases. Experimentally, we considered the three mobility models as follows Random Waypoint, Random Direction and Mobgen Steady State. The experimental results illustrate that the behavior…
