Abstract

As the UAE is classified among the highest countries in road accidents; it’s an urgent necessity to derive proper and effective solutions. One of the well-known solutions is to move to the Intelligent Transportation Systems (ITS). ITS is achieved by the implementation of advanced technologies to help the roads to be smarter, safer and more coordinated. There are different studies and researches published in this area. This thesis is mainly conducted to achieve the same goal, which is increasing the safety on our roads.

The aim of this research is to build a new clustering protocol in the Hybrid Sensor Vehicular Networks (HSVN). HSVN is introduced as a new concept that integrates wireless sensor networks along with vehicular networks to increase the overall performance of both networks and the need of such new protocol in these networks is high. Although there are many published proposals, there is still a need to have a complete protocol that can reduce the shortcomings in the proposed solutions.

The main features in the proposed protocol are creating a balance system by dividing the clustering process overheads between the vehicles in the network and the Road Side Unit (RSU), so instead of relying only on the vehicles’ resources, the RSU shares the process’s overhead by collecting data, calculating weighting factors, and electing suitable cluster heads. Moreover, the proposed protocol reduces the computational and the communication costs by electing two cluster heads for each cluster; one acts as the main cluster head and the other as a standby cluster head. By this feature, if a cluster head moves outside the cluster region, there is no need to run the clustering process again to elect a new cluster head as a standby cluster head exists. Also, one of the main characteristics of the new protocol is minimizing the collision in the system, and consequently increasing the throughput by defining the upper bound of the number of members in each cluster.

The overall performance of the proposed protocol is very good and promises to solve many challenges in the existing protocols. In addition, the results show that this protocol outperforms one of the best existing mobility protocols in terms of the total number of clusters formed in the network, the number of single node clusters, and the saturation throughput of the clusters, the communication overheads and energy consumption reductions.
