The current advancements in the field of wireless networks have led to the emergence and use of intelligent transportation system (ITS) applications on the public transportation to increase road safety and comfort for drivers, passengers, and authorities. Many ITS applications are possible through the use of vehicular ad-hoc network (VANET) communications, such as safety message dissemination, content delivery, and on-road services. Due to high mobility and a large amount of vehicles in a VANET, it is challenging to overcome issues of frequent topology changes and network scalability. To mitigate these issues, a vehicle clustering and management scheme can be applied to the VANET. Towards this goal, a mobility-based clustering scheme with a clustering link quality estimation (CLQE) metric taking both mobility information and link quality estimation into account is proposed in this thesis. The proposed clustering scheme is finally evaluated through the NS-3 simulator and the simulation results show that the proposed scheme outperforms the closely related schemes in most scenarios.
