Welcome to the Fifth ACM International Workshop on VehiculAr InterNETworking (VANET 2008) in beautiful San Francisco! After the success of the previous four events, 2008 is a great year to continue this exciting workshop. The application of short- to medium-range vehicle communication systems (vehicle-to- vehicle as well as vehicle-to-roadside) technologies is closer to reality than ever before and the widespread deployment of a communications infrastructure on the roadways and in production vehicles has the potential to improve transportation and the quality of life in ways not imagined a generation ago. VANET technology is entering a critical phase where academia, industry and governments worldwide are investing significant time and resources to either prepare for a larger scale deployment decision or to already deploy this technology so that its many benefits in the areas of safety, improvement of traffic flow and convenience can be leveraged.
As the change in the name (but not the acronym) of the workshop witnesses, this year we have made a particular effort in broadening VANET scope, both from a horizontal and vertical perspective. Horizontally, the workshop focuses not only on "ad hoc" type of networks (i.e., car-to-car communications), but on vehicular networks in general (including car-to-infrastructure communications). Vertically, the workshop focuses on issues ranging from physical up to the application layer. The technical program committee composition has been adapted to reflect the broadened VANET scope.
This year we received 35 submissions for the regular program of the VANET workshop. Each paper was assigned to three TPC members and received at least three reviews. While for most papers the final decision was straight forward, some papers with heterogeneous reviews were discussed thoroughly by the TPC members. In the end we accepted nine submissions as full papers while the authors of seven additional submissions where invited to present their work as a poster. Due to space constraints and given the excellent quality of this year's submissions, we had to make very tough decisions during this selection process.

A differential OFDM approach to coherence time mitigation in DSRC
As a modification to IEEE 802.11a, the current DSRC standard copes adequately with many of the impairments found in the vehicular wireless channel. However, measurements have shown that these mobile channels exhibit substantially shorter coherence times ...
A measurement study of inter-vehicular communication using steerable beam directional antenna
We provide a measurement study of a single vehicle-to-vehicle (V2V) link using 802.11b as the link layer technology. Our goal is to investigate practical usage of steerable beam directional antennas to improve V2V communications. We conduct extensive ...
How to protect privacy in floating car data systems
Floating Car Data (FCD) is a valuable source of up-to-date traffic information, with a wide range of applications. Active floating car data techniques require drivers to have their vehicles equipped with on-board units regularly transmitting position ...
How much of dsrc is available for non-safety use?
The Dedicated Short Range Communication (DSRC) technology is currently being standardized by the IEEE to enable a range of communication-based automotive safety applications. However, for DSRC to be cost-effective, it is important to accommodate ...
Optimal data rate selection for vehicle safety communications
This paper answers a simple but important question in VANET research: what is the optimal data rate to be used in DSRC-based vehicle safety communications? While it is generally accepted that the default choice is 6 Mbps, this assumption is not rooted ...
Analysis and design of effective and low-overhead transmission power control for VANETs
The control of vehicles' radio communication behavior to deal with the constrained available wireless bandwidth has been identified as a key challenge in VANETs. As an element of congestion control, this paper addresses distributed transmission power ...
Catch-up: a data aggregation scheme for vanets
In-network data aggregation is a useful technique to reduce redundant data and improve communication efficiency. One challenge in data aggregation is how reports can be routed to the same node so that the reports can be merged. Most of existing ...
Data aggregation and roadside unit placement for a vanet traffic information system
In this paper we investigate how a VANET-based traffic information system can overcome the two key problems of strictly limited bandwidth and minimal initial deployment. First, we present a domain specific aggregation scheme in order to minimize the ...
Extending drive-thru data access by vehicle-to-vehicle relay
Recently, some researchers have performed extensive experiments to study the feasibility and performance of vehicle drive-thru access to roadside access points (APs). The experiments demonstrate that the duration of connectivity to the AP is limited. A ...
Understanding the content lifecycle in vehicular applications: first steps towards a generic software platform?
We are creating a generic software platform that supports a wide range of applications running on vehicle mounted Personal Navigation Devices (PNDs). A major aspect is selecting the key abstractions that should make writing applications easy. We derive ...
Runtime infrastructure for simulating vehicle-2-x communication scenarios
Simulations are essential to evaluate Vehicle-2-X Communication applications and to efficiently prepare their deployment. Accordingly, to enable realistic simulations of Vehicle-2-X Communication applications, different kinds of simulators have to be ...
Theoretical analysis of a directional stability-based clustering algorithm for vanets
Clustering has the potential to reduce redundant messaging in MANETs and provide an efficient hierarchical network structure. However, it takes time to form and maintain a cluster structure which also requires additional control overhead. In this paper, ...
Secure and efficient beaconing for vehicular networks
The basis for many VANET applications are periodic beacons carrying information like location, heading and speed. In order to secure beaconing, messages should be signed and carry a certificate to attest valid network participants. In order to reduce ...
Towards an optimized and secure cascade for data aggregation in vanets
We present an analysis of and security extensions to the CASCADE (Cluster-based Accurate Syntactic Compression of Aggregated Data in VANETs) data aggregation technique. CASCADE organizes known vehicles into clusters, the size of which determines both ...
Certificate revocation list distribution in vehicular communication systems
The need to evict compromised, faulty, or illegitimate nodes is well understood in prominent projects designing security architectures for Vehicular Communication (VC) systems. The basic approach envisioned to achieve this is via distribution of ...
Security certificate revocation list distribution for vanet
In a VANET, a certificate authority issues keys and
certificates to vehicles. Each vehicle distributes these certificates to other VANET participants and subsequently signs messages against these certificates. If the certificate authority needs to ...
