Abstract

The demand for mobile communications has been increasing over the last decades. This demand is indicated by various information interchanges during a human's trip on a daily basis. In order to facilitate this demand, the Inter- vehicular Communication (IVC) is one of promising solutions that supports massive information interchanges. The inter-vehicular communication has been investigated and evaluated under several conditions such as in a 3 dimensional environment. The 3-dimensional environment becomes a challenge on the network layer field: the problem in forwarding a data packet. The packet forwarding should show a resilient behavior since it plays the important role to transmit data packets through several issues: the inevitable obstruction, loss connections, and a short duration of connectivity. Therefore, the challenges of modeling and improving such packet forwarding ones are use case specific. This thesis focuses on the network layer since the packet forwarding scheme determines the software that can be modified and engineered in order to optimize this method in particular and very practical use cases. The newly proposed Vehicular-to-vehicular Urban Network (V2VUNet) developed two refined approaches, which extend and improve the forwarding schemes with respect to a more complex 3-dimensional environment. The first approach has the property of limiting the number of intermediate candidates of vehicles by restricting the area of searching. The second approach is the predicting forwarding scheme as the improvement of the area restriction forwarding scheme. Both approaches introduce the Vertical Relative Angle (VRA) as the new parameter in measuring location coordinates of vehicles, particularly in a 3- dimensional area. If, however, VRA is often calculated, it becomes a less significant parameter in most forwarding methods due to its oversimplification in 3-dimensional environments. As a result, the forwarding algorithm's impracticality was overcome by adding a component for the consideration of various road topology levels. This leads to a detailed investigation of such use case under consideration. This books evaluates V2VUNet in many scenarios from a simple 3 dimensional environment to a complex one, and various parameters in or- der to determine and investigate on a suitable solution for such use cases. On one hand, the V2VUNet: the area restriction forwarding scheme shows as a result by now a solution to a 3-dimensional environment. On the other hand, V2VUNet: the prediction forwarding scheme reduces the de- lay significantly. Finally, the enhanced V2VUNet as the combination of the area restriction and prediction forwarding scheme shows the better performance compared to the traditional forwarding scheme.
