The vehicle sector is one of the most exciting application areas for wireless ad hoc networks and pervasive computing technologies. Vehicles are constantly being equipped with more sensors and devices able to collect real-time data on traffic, vehicle condition, passenger health, and so on. Being a relatively new field of application, this area needs tools and methodologies in order to specify requirements and prototype applications. This paper presents a Framework for Pervasive Applications and describes how it can be customized in the case of Vehicular Applications. The framework consists of a set of software requirements, some metrics, and some middleware services for rapid prototyping pervasive applications. In addition, the paper introduces an ongoing project that aims at granting highquality on-road transportation services for fragile food (e.g. wine). In particular, its objective is to provide a system able to monitor several conditions, like temperature, humidity, light, shocks, etc., which carried products are subject to during transportation.

“…This implies that node movement is restricted by factors like road course, encompassing traffic and traffic regulations. Because of the restricted node movement it is a feasible assumption that the VANET will be supported by some fixed infrastructure that assists with some services and can provide access to stationary networks [2]. The fixed infrastructure will be deployed at critical locations like slip roads, service stations, dangerous intersections or places well-known for hazardous weather conditions.…”

Abstract. VANETs have the potential to dramatically increase road safety by giving drivers more time to react adequately to dangerous situations. To prevent abuse of VANETs, a security infrastructure is needed that ensures security requirements like message integrity, confidentiality, and availability. After giving more details on the requirements we propose a security infrastructure that uses asymmetric as well as symmetric cryptography and tamper resistant hardware. While fulfilling the requirements, our proposal is especially designed to protect privacy of the VANET users and proves to be very efficient in terms of computational needs and bandwidth overhead.

“…Previous work such as [5], [6], [7], [8] suggests the use of randomly changing identifiers -so called pseudonyms -to prevent this kind of privacy intrusions. While it is still possible to collect data, associating it with identities over time gets much more complicated if node identifiers are used only for a short period of time.…”

Abstract-Vehicle communication is regarded as one of the major applications of mobile ad hoc networks (MANETs). In these so called vehicular ad hoc networks (VANETs) security and privacy are crucial factors for successful deployment. For example, if each vehicle had a unique identifier and utilized it during its communication, eavesdroppers could easily accumulate location profiles. One approach in the literature proposes to use changing pseudonyms as temporary vehicle identifiers. The basic idea is that the more frequently a vehicle changes its pseudonym, the shorter the period over which it can be tracked will be. However, the impact of such an approach on the system performance has been largely overlooked. Exactly this is our contribution in this paper: we find that changing identifiers has detrimental effects on routing efficiency and increases packet loss. Our investigation provides a set of basic findings that can guide system designers, to achieve both the sought level of protection and performance as well as the right trade-off between the two objectives.I. INTRODUCTION Vehicular ad hoc networks (VANETs) are one of the most promising application scenarios for mobile adhoc networks. With the advent of car-to-car communication, both passenger safety and driving comfort can be improved significantly. A car detecting an icy road could inform follow-up vehicles and thereby prevent accidents. If an accident occurs anyway, inter-vehicle communication could support emergency relief units to reach the accident site faster by warning drivers blocking the road ahead or preemption of traffic lights. Regarding driving comfort, inter-vehicle communication could serve to exchange traffic flow information for improved navigation or intelligent adaptive cruise control.Several research initiatives (e.g. projects like Fleetnet [1]), both in Europe and the U.S., have already produced results in the investigation of vehicular ad hoc networks. For instance, geographic routing has been selected as routing scheme due to its compliance with application needs and its good performance under extremely dynamic network conditions [2].
