To detect the position forging attacks in vehicular ad hoc networks (VANETs) and to improve vehicle passenger safety by means of inter vehicle communication. In the existing system, it presents a model for the performance evaluation of safety message dissemination in VANETs with two classes. In particular, considering the IEEE 802.11 broadcast protocol and 2D Markov modelling. Then the result i...

Vehicular ad hoc networks (VANETs) have become an essential part of the intelligent transportation system because they provide secure communication among vehicles, enhance vehicle safety, and improve driving experience. However, due to openness vulnerability wireless networks, participating vehicles in a VANET are prone variety cyberattacks. To privacy assure authenticity, integrity, nonrepudia...

Vehicular Ad Hoc Networks (VANETs) are characterized by high mobility of nodes and volatility, which make privacy, trust management, security challenging issues in VANETs' design. In such networks, data can be exposed to a variety attacks, the most dangerous is false information dissemination, threatens safety efficiency transportation systems. False emergency messages injected inside attackers...

Exchange of ribosomal subunits (RSU) in the course of protein synthesis has been demonstrated in bacteria." 2 RSU have been shown to be stable during bacterial growth and to be continuously recycled through ribosomes.2 These results suggested that ribosomes dissociate into subunits between successive rounds of protein synthesis. The 30S E. coli RSU binds the initiator tRNA (formylmethionine-tRN...

Multimedia applications are expected to widely deploy over vehicular networks. In order meet the low-latency and high-speed transmission requirements of multimedia applications, edge caching is introduced reduce network traffic delay. Due limited storage cache server, an efficient approach for content management plays a decisive role performance. This paper proposes vehicle-to-infrastructure-ba...

The prediction of received power in the adjacent zone of a Dedicated Short Range Communications (DSRC) system operating inside an arched transportation tunnel is discussed. Wideband directional channel sounding was conducted inside the tunnel, and the gain, angleof-arrival and delay of each propagation path were estimated from the measured data. By simulating application antennas according to t...

We develop joint vehicle tracking and road side unit (RSU) selection algorithms suitable for vehicle-to-infrastructure (V2I) communications. first design an analytical framework evaluating systems based on the extended Kalman filter. A simple, yet effective, metric that quantifies performance is derived in terms of angular derivative a dominant spatial frequency. Second, RSU algorithm proposed ...

In this paper, we provide the first scalable privacy-preserving authentication protocol for VANETs without participation of the nearby RSU. Existing authentication methods for VANETs require the participation of the nearby RSUs. So, bottleneck problem can be occurred as increasing the number of vehicles. Also, the time delay to authenticate the nearby vehicle will increase. In order to minimize...

Studies were undertaken to determine the effect of the Ras suppressor Rsu-1 on Ras signal transduction pathways in two different cell backgrounds. An expression vector containing the mouse rsu-1 cDNA under the control of a mouse mammary tumor virus promoter was introduced into NIH 3T3 cells and the pheochromocytoma cell line PC12. Cell lines developed in the NIH 3T3 background expressed p33rsu-...
