“…The first group of solutions tries to measure physical parameters like time of arrival (TOA), angle of arrival (AOA), time difference of arrival, or the received signal strength [16][17][18]. Other approaches do not rely on physical measurements but rather try to verify the position claims of other nodes based on the logical structure of the network [19].…”

SummaryInter-vehicle communication is regarded as one of the major applications of mobile ad hoc networks (MANETs). Compared to MANETs or wireless sensor networks (WSNs), these so-called vehicular ad hoc networks (VANETs) have unique requirements on network protocols. The requirements result mainly from node mobility and the demands of position-dependent applications. On the routing layer, those requirements are well met by geographic routing protocols. Functional research on geographic routing has already reached a considerable level, whereas security aspects have only been recently taken into account. Position information dissemination has been identified as being crucial for geographic routing since forged position information has severe impact regarding both performance and security.In this work, we first summarize the problems that arise from falsified position data. We then propose a framework that contains different detection mechanisms in order to mitigate or lessen these problems. Our developed mechanisms are capable of recognizing nodes cheating about their position in beacons (periodic position dissemination in most single-path geographic routing protocols, e.g., GPSR). Unlike other proposals described in the literature, our detection system does not rely on additional hardware or special nodes, which would contradict the ad hoc approach. Instead, we use a number of different independent sensors to quickly give an estimation of the trustworthiness of other nodes' position claims. The different sensors run either autonomously on every single node, or they require cooperation between neighboring nodes.The simulation evaluation proves that the combination of autonomous and cooperative position verification mechanisms successfully discloses most nodes disseminating false position information, and thereby widely prevents attacks using position cheating.

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].
