Delay Tolerant Network (DTN) works in challenging conditions where delays are highly expected and links disconnections are very likely. Quality of service (QoS) provisioning in this kind of environment is important. Some of the traditional QoS metrics of bit rate, delay, jitter, packet dropping probability and/or bit error rate are applicable metrics but we think that there are other important metrics...
Since the growth rate of Mobile Ad Hoc networks (MANETs) is increasing, research on routing protocols that improve the conditions for quality of service and propose better strategy, are still opened. Because of MANETs are mobile and infrastructureless, lifetime is one of the important parameters that depend on energy consumption. Energy and traffic per node affect dramatically total energy consumption,...
The recent improvement of wireless communication networks has made possible the use of such networks at the lowest levels of factory automation systems, which typically imposes severe requirements in terms of both real-time performance and dependability. However, Industrial plants represent a hostile environment, for communication systems, due to the presence of different kind of noises. The presence...
The infrared imaging technology is widely used in nondestructive and noninvasive imaging nowadays. The scientists and researches are showing much more interest to the expansion of this technology in medical imaging. The infrared images show a passive relationship between the body surface temperature and tissue metabolism. Determination of the metabolism rate, hyperactive region and depth from the...
In order to assess the viability of using EPAnet source code and the time domain Infrastructure Interdependencies Simulator (I2Sim) for predictive modeling, a critical failure of a municipal water supply was modeled on a university campus. During winter operations, a campus steam plant experienced a failure in operations due in part from an unobserved anomaly in the municipal water supply. The subsequent...
The Disaster Response Network Enabled Platform (DRNEP) is a system that integrates a set of independently developed infrastructure and disaster simulators. This paper describes some of the architectural choices that we made for DRNEP. The overall system uses a master-slave pattern, with one master simulator orchestrating all of the others, based on a central system clock. As the various simulators...
