Exploring the effect of design asymmetry in vehicular communication using visible light communication technology

Abstract

AbstractNature of visible light communication (VLC) in vehicle‐to‐vehicle (V2V) communication is such that it does involve certain aspects of asymmetry. This concept is known issue in wireless networking systems, and it is one of the reasons for the famous node deafness issue. It degrades network performance and it is addressed in various network layers and protocols, especially media access control protocol. This paper investigates effects of asymmetry on communication performance in V2V networks using VLC. Scientific community has recognized asymmetry as an issue that causes communication performance degradation, even in VLC communication. Furthermore, this paper defines different types of asymmetry in V2V communication networks using VLC technology. Finally, simulation experiment is conducted in a controlled environment, which tests the specific types of asymmetry (design) as a cause of network performance degradation. Data and results are analyzed and interpreted; they show that asymmetry (design) is not a significant issue in vehicular communication using VLC. However, results are strictly referring to specific domain, ie, vehicular communication using VLC technology in dense urban environments.
