Nodes in mobile ad-hoc networks communicate each other using the wireless transmission. Many protocols have been proposed allowing the establishment of multi-hop paths to connect source and destination nodes. The absence of a physical link between the nodes and the multi-hop routing lead to a lack of security. Different typologies of attack effective(More)
Car-to-car communication makes possible offering many services for vehicular environment, mainly to improve the safety. The decentralized kind of these networks requires new protocols to distribute information. The advantages that it offers depend on the penetration rate, that will be enough only after years since the introduction, due to the longevity of(More)
Vehicular networking is rapidly growing in the last years, due to its ability of enhancing users everyday-life, in terms of comfort, security and QoS. New services are being implemented and the research activity on the topic is embracing different OSI layers, like the network and application ones. Many efforts have been also given at the PHY layer. In this(More)
MANETs are networks composed of mobile nodes connected using the wireless medium to communicate each other. The MANET nature makes it subject to various types of security leaks. External nodes could interfere with the communication, fair nodes could be compromised at any time by malicious agents. Another issue regards the limited amount of energy available(More)
Ad-hoc networks allow nodes communication without an infrastructure, so they can be used in many environments. This lack of infrastructure introduces many security threats to the nodes in the network. Communication between nodes must be reliable, and protocols for MANETs need to make it possible. Due to the wireless channel and to the possible malicious(More)
Nowadays one of the hot themes in wireless environment research is the application of the newest technologies to road security problems. The interest of companies and researchers, with the cooperation of car manufactures, brought to life and promoted the Vehicular Ad-Hoc Network (VANET) technology. In this work an innovative security system based on VANET(More)
