Towards video streaming in IoT Environments: Vehicular communication perspective

Abstract

Multimedia oriented Internet of Things (IoT) enables pervasive and real-time communication of video, audio and image data among devices in immediate surroundings. Today's vehicles have the capability of supporting real time multimedia acquisition. Vehicles with high illuminating infrared cameras and customized sensors can communicate with other on-road devices using dedicated short-range communication (DSRC) and 5G enabled communication technologies. Real time incidence of both urban and highway vehicular traffic environment can be captured and transmitted using vehicle-tovehicle and vehicle-to-infrastructure communication modes. Video streaming in vehicular IoT (VSV-IoT) environments is in growing stage with several challenges that need to be addressed ranging from limited resources in IoT devices, intermittent connection in vehicular networks, heterogeneous devices, dynamism and scalability in video encoding, bandwidth underutilization in video delivery, and attaining application-precise quality of service in video streaming. In this context, this paper presents a comprehensive review on video streaming in IoT environments focusing on vehicular communication perspective. Specifically, the significance of video streaming in vehicular IoT environments is highlighted focusing on the integration of vehicular communication with 5G enabled IoT technologies, and smart city oriented application areas for VSV-IoT. A taxonomy is presented for the classification of related literature on video streaming in vehicular network environments. Following the taxonomy, critical review of literature is performed focusing on major functional model, strengths and weaknesses. Metrics for video streaming in vehicular IoT environments are derived and comparatively analyzed in terms of their usage and evaluation capabilities. Open research challenges in VSV-IoT are identified as future directions of research in the area. The survey would benefit both IoT and vehicle industry practitioners and researchers, in terms of augmenting understanding of vehicular video streaming and its IoT related trends and issues.

The Use of Meta-Surfaces in Vehicular Networks

“…Today, our on board smart navigator suggests the best route as the shortest one (in time or distance); tomorrow the mobility manager (on board or distributed in the cloud) will plan our commutes on the best connected roads or following the combination of routes and transportation that better fulfill the user's preference and needs. The concept of Internet of vehicles (IoV) has recently emerged just to indicate the need to go beyond the potentialities of vehicular ad-hoc networks (VANETs) and pass from the concept of smartphone to that of smart car, that is a moving connected object in a connected environment [2][3][4][5].…”

Video Streaming in Urban Vehicular Environments: Junction-Aware Multipath Approach

“…It is driven by the vision that the exchange of information between vehicles can be exploited to improve the safety and comfort of drivers while in motion [4][5][6]. One of the most valuable Vehicular Ad-Hoc Networks (VANETs) applications is video streaming [7,8]. Which can offer more understandable and attractive on-road traffic information to drivers and passengers [9,10].…”

“…Their basic application as a camera system for monitoring or supervising a location through video streaming can be extended when they are combined with image processing techniques [1][2][3][4]. In IoT, image sensors may be applied in many fields, some recent contributions use image sensors for surveillance video systems in smart cities [5], for personalized healthcare systems, for recognizing and understanding human activities [6,7] or for video streaming systems in vehicular IoT [8]. Image acquisition systems require a high performance computation in order to handle the large amount of data.…”
