Nowadays, network load is constantly increasing and high-speed infrastructures (1-10Gbps) are becoming increasingly common. In this context, flow-based intrusion detection has recently become a promising security mechanism. However, since flows do not provide any information on the content of a communication, it also became more difficult to establish a ground truth for flowbased techniques ben...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
Communicating with sensors has long been limited either to wired connections or to proprietary wireless communication protocols. Using a ubiquitous and inexpensive wireless communication technology to create Sensor Area Networks (SANs) will accelerate the extensive deployment of sensor technology. Bluetooth, an emerging, worldwide standard for inexpensive, local wireless communication is a viab...
This paper focuses on the development of a method for road network vulnerability analysis, from the perspective of capacity degradation, which seeks to identify the critical infrastructures in the road network and the operational performance of the whole traffic system. This research involves defining the traffic utility index and modeling vulnerability of road segment, route, OD (Origin Destin...
networks and data infrastructures. Instead of just forwarding packets, these intelligent devices implement various policies, like security and quality of service provisioning, that are based on packet content. Consequently, test labs evaluating today’s infrastructures need to simulate real-world traffic that emulates actual user behavior with respect to overall throughput and transaction types....
Mobile agent is an emerging technology that will greatly extend the existing distributed computing mechanisms on computer network. It is evolutionarily being developed on the basis of existing transport and network level protocols within the OSI network model, to achieve autonomy and mobility of programs on application level. Researchers are working on several aspects including conceptual model...
Traffic patterns analysis and solutions for traffic is the emerging field. To determine the patterns of traffic flow and with the help of that data reports can be generated to build the sustainable infrastructure. So that the infrastructures like bridges and fly over will build such that they will be solving problems of the traffic in the current scenarios. To overcome the problem of traffic we...
Supervisory Control and Data Acquisition (SCADA) networks are commonly deployed to aid the operation of large industrial facilities, such as water treatment and distribution facilities, and electricity and gas providers. Historically, SCADA networks were composed by special-purpose embedded devices communicating through proprietary protocols. However, three main trends can be observed in modern...
Intelligent Transportation System (ITS) is a vision which offers safe, secure and smart travel experience to drivers. This futuristic plan aims enable vehicles, roadside transportation infrastructures, pedestrian smart-phones other devices communicate with one another provide safety convenience services. Vehicle (V2V) Infrastructure (V2I) communication in ITS ability exchange speed, heading ang...
The contents of this report reflect the views of the authors, who are responsible for the facts and the accuracy of the information presented herein. This document is disseminated under the sponsorship of Freeway congestion is a major problem in many urban areas. It has been estimated that freeway incidents (events that impede the flow of traffic: accidents, disabled vehicles, etc.) account for...
