Vehicular Visible Light Networks for Urban Mobile Crowd Sensing

Abstract

Crowd sensing is a powerful tool to map and predict interests and events. In the future, it could be boosted by an increasing number of connected vehicles sharing information and intentions. This will be made available by on board wireless connected devices able to continuously communicate with other vehicles and with the environment. Among the enabling technologies, visible light communication (VLC) represents a low cost solution in the short term. In spite of the fact that vehicular communications cannot rely on the sole VLC due to the limitation provided by the light which allows communications in visibility only, VLC can however be considered to complement other wireless communication technologies which could be overloaded in dense scenarios. In this paper we evaluate the performance of VLC connected vehicles when urban crowd sensing is addressed and we compare the performance of sole vehicular visible light networks with that of VLC as a complementary technology of IEEE 802.11p. Results, obtained through a realistic simulation tool taking into account both the roadmap constraints and the technologies protocols, help to understand when VLC provides the major improvement in terms of delivered data varying the number and position of RSUs and the FOV of the receiver.

“…From this point of view, VLC is able to provide a low-cost solution for fast deployment and wide area distribution. Thus, the VLC technology could be used to enable both traffic Infrastructure-to-Vehicle (I2V) and Vehicle-to-Vehicle (V2V) communications [11][12][13][14][15]. Nevertheless, supporting vehicular communications is rather challenging due to the strict requirements (i.e., latencies below 20 ms and high packet delivery ratio) [2,5].…”

An Efficient Task Scheduling Strategy Utilizing Mobile Edge Computing in Autonomous Driving Environment

“…The past decade has seen the development of different wireless access technologies for vehicle-to-everything (V2X) communications, and an extensive set of related use cases have been drafted, each with its requirements [9]. However, visible light communication can be considered to complement other wireless communication technologies which could be overloaded in dense scenarios [10].…”

A Survey on the Roadmap to Mandate on Board Connectivity and Enable V2V-Based Vehicular Sensor Networks

“…The 5GAA is instead promoting C-V2X, which includes both long- and short-range communications based on the cellular standards; in their opinion, short-range C-V2X has the advantage of being included in the same chipset as long-range communications, also promising better performance than IEEE 802.11p due to more advanced solutions at the physical and medium access layers and taking advantage of a more solid industrial ecosystem to guide its future evolution [ 5 ]. Besides these two main technologies, other complementary wireless access technologies are under investigation, such as visible light communication (VLC) and mmWave [ 6 ], in order to improve security, reliability and/or latency in specific scenarios.…”
