The increase in the safety and privacy of automated vehicle drivers against hazardous cyber-attacks will lead to a considerable reduction number global deaths injuries. In this sense, European Commission has focused attention on security communications high-risk systems when receiving cyber-attack such as vehicles. project SerIoT comes up an possible solution, providing useful open reference fr...

Priority queues have a great importance in the study of computer communication networks in which different types of traffic require different quality of service standards. The discrete-time non-preemptive priority queuing model with priority jumps is proposed in this paper. On the basis of probability generating functions mean system contents and mean queuing delay characteristics are obtained....

In the area of Intelligent Transportation Systems the introduction of wireless communications is reshaping the information distribution concept, and is one of the most important enabling technologies. The distribution of real-time traffic information, scheduling and route-guidance information is helping the transportation management systems in their strive to optimize the system. The communicat...

increasing the popularity of sip based services (voip, iptv, ims infrastructure) lead to concerns about its ‎security. the main signaling protocol of next generation networks and voip systems is session initiation protocol ‎‎(sip). inherent vulnerabilities of sip, misconfiguration of its related components and also its implementation ‎deficiencies cause some security concerns in sip based infra...

In the traffic noise investigation framework, the need for a suitable predictive model is quite important, since it allows to evaluate the environmental impact, in case of existing infrastructures, or to design the road network such that noise is minimized, if the infrastructures are going to be built. The traffic noise produced by motor vehicles, as main sources in urban areas, is part of gene...

This paper introduces the special effects of the new developed Regional Satellite Augmentation System (RSAS) as an integration component of the Global Satellite Augmentation System (GSAS) employing current and new Satellite Communications, Navigation and Surveillance (CNS) for improving Air Traffic Control (ATC) and Air Traffic Management and of GPS or GLONASS and enhancement of safety and emer...

Crisis communication during power outages poses several challenges. Frist, the causes of power outages are often events such as severe weather, which also lead to complications. Second, power outages themselves lead to limitations in everyday life. Third, communication infrastructures, that are necessary for crisis communication, are often affected. This work focuses on the communication of the...

Failures in Internet-based services often stem from problems in the underlying enterprise infrastructures that provide the services. We propose an environment called Hercules to test the reliability and performance of large-scale enterprise infrastructures. Hercules contains two major components: (1) a methodology to build a virtual testbed that can accurately emulate any infrastructure topolog...

By pervasiveness of cloud computing, a colossal amount of applications from gigantic organizations increasingly tend to rely on cloud services. These demands caused a great number of applications in form of couple of virtual machines (VMs) requests to be executed on data centers’ servers. Some of applications are as big as not possible to be processed upon a single VM. Also, there exists severa...
