This article considers how information and communications technologies (ICT) can be used by organised crime groups to infringe legal and regulatory controls. Three categories of groups are identified: traditional organised criminal groups which make use of ICT to enhance their terrestrial criminal activities; organised cybercriminal groups which operate exclusively online; and organised groups of ideologically and politically motivated individuals who make use of ICT to facilitate their criminal conduct. The activities of each group are then assessed in relation to five areas of risk: the use of online payment systems, online auctions, online gaming, social networking sites and blogs. It is concluded that the distinction between traditional organised crime groups and the other two groupscybercriminal groups and ideologically/politically motivated cyber groups-is converging, with financially-motivated attacks becoming more targeted. Legislation will need to adapt to deal with new technological developments and threats that organised criminals seek to exploit.
Vehicular ad hoc networks (VANETs) are considered an emerging technology in the industrial and educational fields. This technology is essential in the deployment of the intelligent transportation system, which is targeted to improve safety and efficiency of traffic. The implementation of VANETs can be effectively executed by transmitting data among vehicles with the use of multiple hops. However, the intrinsic characteristics of VANETs, such as its dynamic network topology and intermittent connectivity, limit data delivery. One particular challenge of this network is the possibility that the contributing node may only remain in the network for a limited time. Hence, to prevent data loss from that node, the information must reach the destination node via multi-hop routing techniques. An appropriate, efficient, and stable routing algorithm must be developed for various VANET applications to address the issues of dynamic topology and intermittent connectivity. Therefore, this paper proposes a novel routing algorithm called efficient and stable routing algorithm based on user mobility and node density (ESRA-MD). The proposed algorithm can adapt to significant changes that may occur in the urban vehicular environment. This algorithm works by selecting an optimal route on the basis of hop count and link duration for delivering data from source to destination, thereby satisfying various quality of service considerations. The validity of the proposed algorithm is investigated by its comparison with ARP-QD protocol, which works on the mechanism of optimal route finding in VANETs in urban environments. Simulation results reveal that the proposed ESRA-MD algorithm shows remarkable improvement in terms of delivery ratio, delivery delay, and communication overhead.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
