eHealth service support in IPv6 vehicular networks

Recent vehicular networking activities include public vehicle to vehicle/infrastructure (V2X) large scale deployment, machine-to-machine (M2M) integration scenarios and more automotive applications. eHealth is about the use of the Internet to disseminate health related information, and is one of the promising Internet of Things (IoT) applications. Combining vehicular networking and eHealth to record and transmit a patients vital signs is a special telemedicine application that helps hospital resident health professionals to optimally prepare the patients admittance. From the automotive perspective, this is a typical Vehicle-to-Infrastructure (V2I) communication scenario. This proposal provides an IPv6 vehicular platform which integrates eHealth devices and allows sending captured health-related data to a Personal Health Record (PHR) application server in the IPv6 Internet. The collected data is viewed remotely by a doctor and supports a diagnostic decision. This paper introduces the integration of vehicular and eHealth testbeds, describes related work and presents a lightweight auto-configuration method based on a DHCPv6 extension to provide IPv6 connectivity for resource constrained devices.

V2V2I: Extended inter-vehicles to infrastructure communication paradigm

We consider the problem of providing ubiquitous IPv6 Internet connectivity to vehicles compliant with IEEE WAVE standard. In particular, we take advantage of two realistic technology trends. On the one hand, IEEE 802.11p interfaces should be mandatory on the On-Board Units (OBUs) but the Road-Side Units (RSUs) deployment will not be immediate. This unavoidable deployment phase slows down the services availability and ITS protocols deployment. On the other hand, car manufacturers have already started equipping their OBUs with 3GPP cellular interfaces (provisioning for LTE) to enable specific car services (remote diagnosis, enter-tainment). We propose to explore the area of inter-vehicles to infrastructure (V2V2I) communication paradigm. We also set fundamental technical requirements enabling IPv6-ready OBUs to access the infrastructure during this deployment phase, and ensure ubiquitous IPv6 Internet access later over LTE. In particular, we compare V2V2I with other vehicular networking models and establish the technical constraints and limits of this paradigm. In order to access the global infrastructure, we satisfy two essential networking requirements for 802.11p-only vehicles: global addresses and specific routes.

Analyzing dynamic IPv6 address auto-configuration techniques for group IP-based vehicular communications

Dynamic IPv6 addressing and routing configuration in vehicular networks is an important challenge that has attracted a fair amount of attention recently. Early proposals adapted fixed-infrastructure and MANET models and thus inherited their latency and overhead. Later, researchers relaxed some of the often restrictive assumptions (e.g., Router Advertisement TTL extension) but still focused on certain limited scenarios. Very recently, in the wake of the emerging concept of Future Internet, a general questioning arose on whether one naming and addressing model suits every network topology. Along this line of research, the present article poses the terms of this problem in the IP-based vehicular communications area and aims at giving one solution space instance based on the Vehicle Identification Numbers (VIN) namespace. This article advances the state-of-the-art as follows: (1) It presents a comprehensive and detailed tutorial of the main dynamic IPv6 auto-configuration approaches. (2) It gives the specifics of Future Internet paradigm as applied to vehicular networking and presents a novel approach for group and infrastructure communications based on VIN namespace. (3) It offers a comprehensive feature and analytical comparison to evaluate the proposals that fit best our communication paradigm.

A Review of Network Mobility Protocols for Fully Electrical Vehicles Services

This article reviews IETF network mobility techniques and ISO data protocols involved in electrical charging which represent key enablers for an IP-based platform composed of backend servers, networks of fixed charging stations and of mobile Fully-Electrical Vehicles (FEVs). This platform further allows services for ensuring drivers confidence in reaching arbitrary destinations, despite well-known limitations such as battery technologies, and mitigating the risks involved by the use of inherently insecure basic IP datagram exchanges.

VIN6: VIN-based IPv6 provider independent addressing for future vehicular internet communications

Recent years witnessed growing concerns regarding scalability of todays Internet architecture. Universality of the single IP numbering space is one cause of unbound growth of entropy and inter-domain routing tables in the core network. Recently, the IAB proposed to review the Internet addressing architecture to separate name and location spaces. In this paper, we propose an instance of VIN-based IPv6 addressing, compatible with other Future Internet efforts, to tackle this issue with regards to the vehicular communications. We design a global hierarchical identification space of up to 235 unique and distinct vehicles per manufacturer (216 manufacturers). An original method of mapping these identifiers to addresses and guarantee the uniqueness conservation is proposed. The objective is to create a sustainable addressing architecture for vehicular communications and introduce the manufacturer as a new vehicular services provider. We also propose a network architecture design that allows to use pseudonyms as a way to tackle identity privacy concerns.

eHealth Service Support in Future IPv6 Vehicular Networks

Recent vehicular networking activities include novel automotive applications, such as public vehicle to vehicle/infrastructure (V2X), large scale deployments, machine-to-machine (M2M) integration scenarios, and more. The platform described in this paper focuses on the integration of eHealth in a V2I setting. This is to allow the use of Internet from a vehicular setting to disseminate health-related information. From an eHealth viewpoint, the use of remote healthcare solutions to record and transmit a patient’s vital signs is a special telemedicine application that helps hospital resident health professionals to optimally prepare the patient’s admittance. From the automotive perspective, this is a typical vehicle-to-infrastructure (V2I) communication scenario. This proposal provides an IPv6 vehicular platform, which integrates eHealth devices and allows sending captured health-related data to a personal health record (PHR) application server in the IPv6 Internet. The collected data is viewed remotely by a doctor and supports his diagnostic decision. In particular, our work introduces the integration of vehicular and eHealth testbeds, describes related work and presents a lightweight auto-configuration method based on a DHCPv6 extension to provide IPv6 connectivity with a few numbers of messages.

Integration of eHealth Service in IPv6 Vehicular Networks

Several convenience and efficiency applications have been proposed as part of recent vehicular networks (a.k.a. VANET) activities. Among these proposals, eHealth has often been studied as a time-critical application to emulate an ambulance. The Vehicle-To-Infrastructure (V2I) setting is the typical communication scenario to carry out the data in this case. From a user perspective, combining vehicular networking and eHealth to record and transmit a patient’s vital signs is a special telemedicine application that helps hospital resident professionals to optimally prepare the patient’s admittance. The current proposal pro-vides an IPv6 vehicular platform which integrates eHealth devices and allows sending captured user health-related data to a Personal Health Record (PHR) application server on the IPv6 Internet. The collected data are viewed remotely by a doctor and supports diagnostic decision. The resulting platform is then compared to the state-of-the-art related architectures.
