“…The research community has already started to investigate the feasibility and the propagation dynamics of worms in mobile networks [5,6,34,29]. While no large-scale mobile worm outbreak has been reported so far, several reports of worms spreading over the Bluetooth protocol in a cell-phone environment exist [7,12].…”

Abstract. The popularity of handheld devices has created a flurry of research activity into new protocols and applications that can handle and exploit the defining characteristic of this new environment -user mobility. In addition to mobility, another defining characteristic of mobile systems is user social interaction. This paper investigates how mobile systems could exploit people's social interactions to improve these systems' performance and query hit rate. For this, we build a trace-driven simulator that enables us to re-create the behavior of mobile systems in a social environment. We use our simulator to study three diverse mobile systems: DTN routing protocols, firewalls preventing a worm infection, and a mobile P2P file-sharing system. In each of these three cases, we find that mobile systems can benefit substantially from exploiting social information.

“…Our result is consistent with the findings in [12] which show that epidemiological models greatly overestimate the spreading rate of worms in MANET. On the other hand they refute the findings in a preliminary study of worm spreading in VANET [13].…”

“…A worm attack on VANET may interfere with critical applications such as engine control and safety warning systems hence resulting in serious congestion on the road networks and large-scale accidents. While there has been much research on the dynamics of worm spreading on the Internet [10,9,11], there has been, to our knowledge, very few studies of worm epidemics in mobile ad hoc network in general [12] and vehicular ad hoc networks in particular [13]. Such studies are critical for assessing the risks associated with worm attacks on VANET, and devising effective counter measures and techniques for their detection and mitigation.…”

Abstract. Vehicular ad hoc networks (VANET) are likely to become one of the most relevant forms of mobile ad hoc networks (MANET). An important challenge in large scale deployment of these networks is securing them against potential cyberattacks. An attack scenario with potentially catastrophic consequences is the outbreak of a worm epidemic in these networks, which can start by infecting the onboard computer of a single vehicle and spreads through the whole network by transmission from vehicle to vehicle. In this paper we investigate the outbreak of worm epidemics in highway traffic by means of modelling and large-scale simulations. Our study combines a realistic model of node movements in VANET with a velocity-dependent shadow-fading model of wireless links between VANET nodes, and takes into account the full topology of the resulting ad hoc networks. We perform stochastic simulations of worm spreading under various traffic conditions, both in the absence and in the presence of preemptive immunization and an interactive patching process. IntroductionVehicular ad hoc networks (VANET) are created by vehicles equipped with short and medium range wireless communication. Communication is possible between vehicles within each other's radio range, and with fixed gateways along the road. The ability of vehicles to communicate directly with each other via wireless links and form ad hoc networks is opening up a plethora of exciting applications [1][2][3]. These include safety applications, real-time traffic monitoring and management and broadband wireless access for automobile users, to name a few. Creating high-speed, highly scalable and secure vehicular networks presents a formidable research challenge. This is due to a combination of the highly dynamic nature of VANET, the relatively high speeds involved and the potentially very large scale of these networks. In the last few years researchers have intensively investigated many aspects of vehicular communications, and much progress has been made [4,5]. Surprisingly, very few groups have addressed the security threats to VANET [6], and in particular those resulting from cyberattcks by viruses and other form of malicious software (malware).

In [3] the authors investigated the impact of communications and mobility effects on worm propagation mechanisms in MANETs, where they found that network delays and channel congestion had a large impact on the UDP-based worm propagation behavior.…”

“…They also provided a set of relatively simple analytical models that reproduced these communications. In [4] the authors discussed the effect of mitigation techniques on the UDPbased worm spread in MANETs and provided analytical models and simulation experiments to validate their findings. The authors represented the mitigation technologies as having a constant detection time represented by a lifetime parameter of the worm, after which the worm dies and stops infection of other hosts.…”
