Wireless Mesh Networks (WMN) have proven to be a key technology for increased network coverage of Internet infrastructures. The development process for new protocols and architectures in the area of WMN is typically split into evaluation by network simulation and testing of a prototype in a test-bed. Testing a prototype in a real test-bed is time-consuming and expensive. Irrepressible external ...

Background: Given that a significant part of deaths due to traffic accidents are preventable in the prehospital phase, so it seems necessary to have an instrument to identify and measure the factors affecting it. This study aimed to develop and psychometrically assess an instrument for measuring preventable prehospital mortality due to traffic accidents. Methods: The study is a mixed qualitati...

Reliable and secure communication is at the heart of well being and delivery of critical services in today’s society, making power grids, financial services, transportation, government and defence highly dependent on ICT networks. Regional and national emergencies are characterised by their devastating effect on human lives and the society’s ability to function. Unfortunately, rescue operations...

We discus some frequently neglected issues relating to corporate communication infrastructures. The perception of services like e-mail as infrastructural -and thus less interesting -lies at the heart of corporate ignorance regarding their strategic capabilities. This may cause major problems in the near future, when inadequate communication infrastructures may hamper the successful uptake of st...

Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...

Wide Area Measurement Systems (WAMS) enable real time monitoring and control of smart grids by combining digital measurement devices, communication and control systems. As WAMS consist of various infrastructures, they imply complex dependencies among their underlying systems and components of different types, such as cyber, physical and geographical dependencies. Although several works exist in...

Communication and transportation networks are among the most important infrastructures critically involved in the development of different countries. The structural and tectonic position of Iran causes significant damage to its communication networks every year. Therefore, it is essential to adopt an integrated and flexible approach for assessing seismic risk in terms of available indicators. T...

Interconnecting networks adopting Fast Optical Switches (FOS) can achieve high bandwidth, low latency, and power consumption. We propose demonstrate a novel interconnecting topology based on FOS (FOSquare) with distributed fast flow control which is suitable for HPC infrastructures. also present an Optimized Mapping (OPM) algorithm that maps the most communication-related processes inside rack....

Abstract Supervisory Control and Data Acquisition (SCADA) systems have become critical for companies to save a lot of time money connectivity more important than ever in the era Industry 4.0. That’s why organizations are looking integrated platforms that can simulate industrial traffic between different locations around globe. The present work succeeded simulating data information through SCADA...
