Towards characterising and classifying communication-based automotive applications from a wireless networking perspective

Abstract

Together, the Dedicated Short Range Communication (DSRC) and Vehicular Ad Hoc Network (VANET) technologies provide a unique opportunity to develop and introduce various types of communicationbased automotive technologies to the marketplace. To date, many applications have been identified by the automotive community. Given the large number and diverse nature of these applications, it is advantageous to develop a systematic classification methodology to facilitate future DSRC and VANET research. Toward this objective, in this paper, we present a study that goes through two major steps: characterisation and classification. First, we focus on a set of representative applications and characterise them with respect to plausible application-and networking-related attributes. The characterisation process not only strengthens our understanding of the applications but also sets the stage for the classification step since it reveals numerous application commonalities. Thus, we have categorised the given applications into seven generic classes, with the consideration of balancing the trade-off between exploiting as many application similarities as possible while preserving their salient differences. This is of paramount importance to facilitate performance analysis of newly designed protocols. Finally, we have identified key performance metrics for each class of applications, which, we hope, could bridge the gap between the automotive and wireless networking communities. Accordingly, the proposed classes are envisioned to play a dual-role: facilitate application simulation and performance evaluation and guide DSRC and VANET protocol research and development.

OSA: A Vanet application focused on fuel saving and reduction of CO2 emissions

“…Description of elements in Table 2 is given by Bai, Krishnan and Sadekar (2006) and it is exposed in the next paragraphs. With this two software tools, the framework named Veins (Vehicles in Network Simulation) was utilized.…”

Modeling and Simulation of Vehicular Networks: towards Realistic and Efficient Models

“…This is a very important shortcoming, given that a large number of proposed Intelligent Transportation System (ITS) applications carried over VANETs can affect the movement of the vehicles (this is especially the case with traffic management applications), thus rendering the trace-based models inadequate for any application with the feedback loop between the traffic and networking models. A vivid example of such application is Congested Road Notification (Bai et al (2006)), which aids the vehicles in circumventing congested roads, thus directly affecting the mobility of the vehicles through the network communication. A characteristic that distinguishes the dedicated traffic models from the trace-based ones, capability to support the feedback loop between the mobility model and the networking model, is an important reason for adopting the more flexible dedicated traffic models.…”

“…The data models used in the current simulators, such as NS-2 (Network Simulator 2 (n.d.)), JiST/SWANS/STRAW (Choffnes & Bustamante (2005)), and NCTU-NS (Wang et al (2003)), rely on discrete event simulation, where different protocols of the network stack are executed based on the events triggered either by upper layer (e.g., an application sends a message to the networking protocol) or by lower layer (e.g., the link layer protocol notifies the network layer protocol about the correct reception of the message). (Bai et al (2006)), entertainment (Tonguz & Boban (2010)), etc.) services are also envisioned, creating incentive for faster adoption of the technology.…”

On the Feasibility of Using 802.11p for Communication of Electronic Toll Collection Systems

“…The proposed vehicular communication technology, known as the Dedicated Short Range Communication (DSRC), is currently being standardized by the IEEE [18,19] and is known as 802.11p. Many major car manufacturers have responded positively and are actively working together to develop practical application of this promising technology [20,21]. Although the primary purpose of 802.11p is to enable communication-based automotive safety applications, such as cooperative collision warning (CCW), this new standard also facilitates for a range of nonsafety applications, from electronic toll collection to multimedia downloading.…”
