Network on wheels: Leveraging vehicular communication to newer heights for intelligent transportation system

Abstract

Quick progressions in the improvement of intelligent and smart machines and parallel advancement of technologies in the field of wireless communication have achieved more prominent statures. However, certain issues still pertain when one tries to develop a hybrid network. A heterogeneous vehicular network is developed with the idea of utilizing the readily available infrastructures such as long-term evolution and dedicated short-range communication, which is economically profitable. We discussed some of the issues that arise when we converge dedicated short-range communication and long-term evolution and addressed certain issues such as creating a link to communicate between two different technologies that can be achieved by considering the baseband implementations of the two technologies in the physical layer and Media Access Control (MAC) levels. The efficiency of the system is observed at three distinguish multimedia transmission where a text file, audio file, and an image file are transmitted and the system’s performance is observed by analyzing the bit error rate vs signal-to-noise ratio for each of the files. The results obtained justified that it is possible to create a heterogeneous vehicular network (HetVNet) even with the presence of certain elements diversities in the characteristics of long-term evolution and dedicated short-range communication.
