Résumé : |
Currently, the Intelligent Transportation Systems (ITS) are increasingly studied as well in the community of
research in industries (automobile, telecommunications, etc). Indeed, the implementation of ITS applications
may in the short term to improve road safety, effectively increasing the use of roads, reduce congestion and
traffic jams, reduce the impact of vehicles on the environment, etc.
However, several problems must be solved before being able to conceive such applications, among which the
self-organization of inter-vehicles communications has a privileged place.
In this thesis, we focus on the optimization of VANET architecture. Initially, we are interested in two types
of ad hoc networks WSN (Wireless Sensors Network) and VSN (Vehicular Sensors Network) where their main
characteristics and applications are surveyed and a comparison between them is presented. Then, we tackle the
principal constraint in the vehicular networks i.e. the mobility. In fact, the exact prediction of mobility of the
nodes forming the network is very important in the simulation of VANET networks. Hence, a comparative study
between two mobility models is made after a presentation of a set of related works dealing with mobility models
in vehicular networks. Finally, we propose a self-organization mechanism called MCAV based on clustering,
able to efficiently adapt to the vehicular network characteristics and applications. This advocated technique is
evaluated by a combination of network simulator (NS-2) and a realistic mobility model VanetMobiSim. |
