Vehicular networks represent a research area of significant importance in improving the safety, efficiency and sustainability of transportation systems. One of the key research problems in vehicular networks is real-time data dissemination, which is crucial to the satisfactory performance of many emergent applications providing real-time information services in vehicular networks. Specifically,...

Failure detectors are one of the fundamental components for maintaining the high availability of vehicular cloud computing. In vehicular cloud computing, lots of RSUs are deployed along the road to improve the connectivity. Many of them are equipped with solar battery due to the unavailability or excess expense of wired electrical power. So it is important to reduce the battery consumption of R...

Access control of message is required when certain selected vehicles are granted access to information, instead of all vehicles within communication range. In these situations an access policy (consisting of attributes as road situation and vehicle type) is built into the vehicle and messages are encrypted using these access policies. Only valid vehicles possessing these attributes are able to ...

This article presents a comprehensive survey of routing protocols proposed for routing in Vehicular Delay Tolerant Networks (VDTN) in vehicular environment. DTNs are utilized in various operational environments, including those subject to disruption and disconnection and those with high-delay, such as Vehicular Ad-Hoc Networks (VANET). We focus on a special type of VANET, where the vehicular tr...

In Vehicular Ad-hoc Network (VANETs), security is a primary concern, as it affects traffic safety. Authentication in essence is an important security requirement to avoid attacks on vehicular communication. To provide authentication with some privacy to the users, we propose an authentication framework that uses pseudonyms, which are self-generated are used as key value in communication among v...

Vehicular Adhoc Network (VANET) is a special type of Intelligent Transport System (ITS), where the mobile nodes are cars, two wheelers, trucks, buses etc., that move on well organized and predefined roads in both direction at very high speed. Following traffic rules, the vehicles provide communication with each other directly (Inter Vehicle Communication IVC) or indirectly through the Road Side...

Mutations of the Drosophila melanogaster suppressor of sable [su(s)] gene, which encodes a 150-kDa nuclear protein [Su(s)], increase the accumulation of specific transcripts in a manner that is not well understood but that appears to involve pre-mRNA processing. Here, we report biochemical analysis of purified, recombinant Su(s) [rSu(s)] expressed in baculovirus and in Escherichia coli as malto...

The vehicles in the fifth-generation (5G)-enabled vehicular networks exchange data about road conditions, since message transmission rate and downloading service have been considerably brighter. shared by are vulnerable to privacy security issues. Notably, existing schemes require expensive components, namely a road-side unit (RSU), authenticate messages for joining process. To cope with these ...

Isoleucine, leucine and valine are synthesized via a common pathway in which the first reaction is catalysed by AHAS (acetohydroxyacid synthase; EC 2.2.1.6). This heterotetrameric enzyme is composed of a larger subunit that contains the catalytic machinery and a smaller subunit that plays a regulatory role. The RSU (regulatory subunit) enhances the activity of the CSU (catalytic subunit) and me...
