INVISIBLE2.0: an Enhanced Interference-based Handover Technique for Visible Light Communications in Vehicular Networks
Résumé
During the last decade, the exponential growth of mobile devices and their applications, especially in the framework of the Internet of Things (IoT), induced an enormous demand for radio frequency (RF) technologies. However, the lack of sufficient resources led to the spectrum crunch phenomenon, pushing researchers to explore alternative technologies outside the RF band. Among many strategies that have been adopted to maximize the exploitation of these precious resources, Visible Light Communication (VLC) demonstrates a huge capacity to complement conventional RF technologies in plenty of applications. In this work, we investigate the coexistence of VLC and the long-term evolution (LTE) cellular network in a vehicular environment. The coordination of data transmission among different technologies is managed through a novel vertical handover mechanism, namely INVISIBLE2.0. This technique is triggered by the error probability to meet the 3GPP requirements on packet reception ratio while endorsing VLC as the preferred technology bearer. We demonstrate that INVISIBLE2.0 achieves a more stable latency, and energy efficiency based on a detailed power model represented here for VLC and LTE.
