Information infrastructures, such as the Internet and Computational Grids, have enabled a networked computing and communication environment. Although many organizations depend on network-centric information operations to support critical missions, existing information infrastructures provide little guarantee of the dependability of network-centric computing and communication. This paper discuss...

Supervisory Control and Data Acquisition systems are basically Process Control Systems, designed to automate systems such as traffic control, power grid management, waste processing etc. Conventionally, SCADA is connected only in a limited private network because SCADA is considered a critical infrastructure, and connecting to the internet may put the society on jeopardy, SCADA operators hold b...

Our living environment is under real threat of various global issues like global warming, rising sea-level, changing weather patterns, floods and hurricanes etc as well as local issues likes housing affordability, traffic congestion, pollution, health and environmental degradation etc. All these issues are inter-related and cities are the major contributor. These issues can’t be addressed in is...

Wide area measurement system (WAMS) is one of the essential components in the future power system. To make WAMS construction plans, practical models of the power network observability, reliability, and underlying communication infrastructures need to be considered. To address this challenging problem, in this paper we propose a unified framework for WAMS planning to cover most realistic concern...

This paper deals with the optimization of data routing processes and with optimization of deployed quality of service mechanisms in computer networks. The paper addresses the problems related to requirement of monitoring and managing of network infrastructures with attention given to data routing mechanisms in network and often used QoS mechanisms. This paper also presents the concept of tool f...

Due to their inherent features, P2P networks have proven to be effective in the exchange of data between autonomous peers. Unfortunately, these networks are subject to various security threats that cannot be addressed readily since traditional security infrastructures, which are centralized, cannot be applied to them. Furthermore, communication reliability across the Internet is threatened by v...

Road traffic is drastically increasing in big cities around the world. In order to enable a flexible management of this traffic, Intelligent Transportation System (ITS) solutions are relying on emergent ubiquitous, mobile, and communication technologies, particularly intelligently deal with limited capacities existing road infrastructures. While intelligence left autonomous connected vehicles a...

Vehicular communications, referring to information exchange among vehicles, pedestrians, and infrastructures, have become very popular and been widely studied recently due to its great potential to support intelligent transportation and various safety applications. Via vehicular communications, manually driving vehicles and autonomous vehicles can collect useful information to improve traffic s...

Hybrid traffic modeling and simulation provide an important way to represent and evaluate large-scale traffic networks at different levels of details. The first level, called “microscopic” allows the description of individual vehicles and their interactions as well as the study of driver’s individual behavior. The second, based on the analogy with fluidic dynamic, is the “macroscopic” one and p...
