Description:	Vehicle Ad-hoc Network (VANET) is the direct application of Mobile Ad-hoc Network (MANET) in which the nodes are represented by vehicles moving in city or highway scenario environment. The main goal of such networks is to create a network where the vehicles can exchange data by communicating with other vehicles or with Road Side Unit. These types of communications have led to the emergence of Intelligent Transportation System, using this to apply various applications that can provide a safer driving and more efficient one. Deployment of VANETs relies on routing protocols to transmit the information between the nodes. Different routing protocols that have been designed for MANET have been proposed to be applied in VANETs. However, there are many challenges when it comes to deploying these routing protocols in VANET due to its unique characteristics. In this work we deal with the well-known MANET proactive Optimized Link State Routing protocol (OLSR). The deployment of OLSR in VANET gives moderate performance, this is due to its necessity of maintaining an updated routing table for all possible routes. The performance of OLSR is highly dependent on its parameter, thus finding optimal parameters configurations that best fits VANETs features and improves the network’s quality of services is essential before its deployment. Therefore, we aim at OLSR parameters configurations by coupling two stages, a procedure for optimization which is carried out by a Modified Harmony Search Algorithm based on embedding two popular selection methods in its memory; roulette wheel selection and tournament selection and a simulation stage represented by MATLAB simulator (based on a highway scenario). The experimental analysis shows that the optimized OLSR parameters obtained by our proposed approach has achieved promising results when compared with original OLSR, basic Harmony Search Algorithm and Particle Swarm optimization in terms of global network quality of services performance.,Master of Computer Science,Certification of Master's / Doctoral Thesis" is not available"
