This paper describes a tool for the design, simulation and analysis of real-time systems, ranging from simple scenarios with a few types of tasks on a single node to very complex architectures consisting of multiple nodes interconnected with a network and sharing a set of hardware and software resources. The tool is based on a discrete event simulation library, a scripting language describing t...

This paper presents a desktop application tool for visualizing simulations of Mobile Ad Hoc Networks with caching capabilities. This tool uses the log files generated by any network simulator that implements the required log format and the mobility file with the NS2 format in order to represent both, the network traffic and the mobility respectively. This tool works as an interface to represent...

This paper provides an investigation of power distribution network (PDN) performance by a full-wave prediction tool and by experimental measurements. A set of six real boards characterized by increasing complexity is considered in order to establish a solid base for behaviour understanding of printed circuit boards. How the growing complexity impacts on the board performance is investigated by ...

This paper introduces a multi-paradigm dynamic system simulator based on discrete time and discrete event formalism for simulating a supply chain as a complex adaptive system. Little is known about why such a diversity of supply chain structures exist. Simulating dynamic supply chain networks over extended periods using the multiparadigm dynamic system simulator allows us to observe the emergen...

In this paper, we propose a flow-level simulator called FSIM (Fluid-based SIMulator) for performance evaluation of large-scale networks, and verify its effectiveness using our FSIM implementation. The notable feature of our flow-level simulator FSIM is fast simulation execution compared with a conventional flow-level simulator. For accelerating simulation execution speed, our flow-level simulat...

In the context of Long-Term Evolution (LTE), the next generation mobile telecommunication network, femtocells are lowpower base stations that efficiently provide coverage and capacity indoors. This paper presents a computationally efficient dynamic system-level LTE simulator for enterprise femtocell scenarios. The simulator includes specific mobility and traffic and propagation models for indoo...

This paper describes an experimental "distributed" programming system which makes it possible to create multi-computer programs and to run them on computers connected by the ARPA computer network (ARPANET).1 The programming system, which is called McROSS (for Multi-Computer Route Oriented Simulation System), is an extension of a singlecomputer simulation system for modelling air traffic situati...

This paper first represent the basic conceptions of anonymous communication, then introduce the fundamentals in Anonymous Communication. Afterwards, we went deep to the classification of anonymous network topological, therefore we could get a better understanding on P2P anonymous communication system. We also systematically analyzes the existing node-select algorithms. Furthermore, we propose a...

In research of overlay networks, simulator takes a very important role. However, popular simulators, such as ns and PlanetLab can’t meet the scale and performance requirement of overlay research. Although it is necessary for overlay researchers to observe activities of million nodes, current simulators can not give such simulation result. To improve the overlay network research efficiency, we d...
