A Mutual Awareness Mechanism of Inter-MVFs (Mobile Virtual Fences) to Support Connected Car Service

Abstract

In this paper, we present a mutual awareness mechanism among lots of MVFs(Mobile Virtual Fences) to configure Connected cars service in VANETs(Vehicular Ad hoc Networks). If the MVFs, as our previous researches, mounted on each car are recognized and constructed to each other, the service environment of connected car can be configured and simulated. So it is necessary to have a mechanism that the moving MVFs automatically detect according to the speed. The proposed mutual awareness mechanism is implemented by exchanging messages among inter-MVFs based on context-aware computing. As a result, when the MVFs are mutually recognized, they are basically simulated in a connected car service. Therefore, in the future, the proposed mechanism will be contribute to improve the reliability, safety, and efficiency in the era of autonomous vehicles.

Topological Sequence Recognition Mechanism of Dynamic Connected Cars Using the Connected Mobile Virtual Fence (CMVF) System for Connected Car Technology

“…The CMVF server performs the role of an ITS, and the CMVF client using a smartphone acts on behalf of a vehicle [10]. Thus, a smartphone itself, instead of attaching additional devices to existing vehicles, becomes an independent CMVF client; it maintains a dynamic awareness radius that senses and reacts according to the vehicle's speed, which allows context-aware computing within its virtual boundary [10,24]. Thus, vehicle-to-vehicle (V2V) communication occurs when vehicles with attached smartphones as CMVF clients are connected to clients of other vehicles through mutual awareness [4,24].…”

The mutual awareness mechanism already developed is implemented by exchanging integrated messages among CMVF clients based on context-aware computing [24]. Here, integrated messages composed by the integrated messages framework, which was designed earlier, are added with context-aware information of CMVF clients after comparing and analyzing common fields of Basic Safety Message (BSM) and Cooperative Awareness Message (CAM)/Decentralized Environmental Notification Message (DENM) [25][26][27][28].…”
