The increasing complexity and low-power constraints of current Wireless Sensor Networks (WSN) require efficient methodologies for network simulation and embedded software performance analysis of nodes. In addition, security is also a very important feature that has to be addressed in most WSNs, since they may work with sensitive data and operate in hostile unattended environments. In this paper...

In this paper we focus on the modeling and simulation of a distribution service network (DSN) for urban rail transit hub (URTH). Firstly, using the method of complex networks, the concept of DSN is proposed. Secondly, a model of DSN is formulated which consists of: i) a distribution entity topology network, ii) a distribution transport function network and iii) a distribution service function n...

conclusions: the patients' waiting times and the number of patients waiting to receive services in both shifts could be reduced by using multitasking persons and reallocating them to the time-consuming stage of filling prescriptions, using queuing theory and simulation techniques. background: hospital pharmacy is responsible for controlling and monitoring the medication use process and ensures ...

this paper describes the application of process integration principles to the design of oil refineries hydrogen network. in this regard, a design hierarchy as well as heuristics and required guidelines are proposed. the recommended rules compensate lack of procedure to the design and make the design process easier. the guiding principles of the design are based upon pinch technology and extendi...

Real-time network simulation enables simulation to operate in real time, and in doing so allows experiments with simulated, emulated, and real network components acting in concert to test novel network applications or protocols. Real-time simulation can also run in parallel for large-scale network scenarios, in which case network traffic is represented as simulation events passed as messages to...

Simulation is an important tool in planning. Large simulations require a lot of memory and processing time. In many cases the long simulation times reduce the usability of simulation. In this paper, aspects affecting distributed simulation have been studied, including hardware, software and network related issues. Experiments have been carried out with a distributed simulator, Diworse. Simulati...

In the paper we will describe how the software agent paradigm can be a powerful and versatile simulation tool to model and study complex systems. Software agents allow to approximate the behaviour of complex systems under several scenario conditions. In some cases, software agents can also be used to approximate solutions to difficult problems occurring in complex systems. To support our positi...

Simulation studies have been extensively adopted in the networking research community. Nevertheless, the performance of the software components running within the network devices is often not modeled by generic network simulators. This aspect is particularly important in wireless sensor networks (WSN). As motes present very limited computing resources, the overhead of the software components ca...
