Network Simulators: a Developer’s Perspective
نویسنده
چکیده
In the paper, we compare simulation modes and programming interfaces of three popular network simulators: ns-2, J-Sim and OPNET. Our observations and conclusions are based on a “realworld” FTP application case study, and also on our earlier projects.

Comparative study of computer simulation softwares
One of the methods for analyzing systems is simulation. Network simulation is a technique that models the behavior of the network by performing transaction calculations between different network entities and using mathematical formulas and taking observations from network products. A network simulator is a piece of software or hardware that predicts the behavior of a computer network without a ...
متن کاملCompact Lossy Inductance Simulators With Electronic Control
In this paper two R‑L network simulator configurations employing a single VDDIBA, one resistance and one grounded capacitance are presented. The first configuration is a grounded series resistor-inductor (R‑L) network simulator and the second configuration is intended for grounded parallel resister-inductor (R‑L) circuit simulation. Both the proposed circuits enjoy several beneficial features s...
متن کاملStudy on Influence of Cognitive Load for Software Developer's Performance using BPNN Algorithm
The development process involved developers contribution based his/her cognitive thinking in the real time process. The developer’s performance is dynamic as per their cognitive load. The cognitive load is un-deterministic as well hidden and integrated in the developer’s process. This paper attempt to identify software developer cognitive measure which influences the development process using n...
متن کاملPrediction of methanol loss by hydrocarbon gas phase in hydrate inhibition unit by back propagation neural networks
Gas hydrate often occurs in natural gas pipelines and process equipment at high pressure and low temperature. Methanol as a hydrate inhibitor injects to the potential hydrate systems and then recovers from the gas phase and re-injects to the system. Since methanol loss imposes an extra cost on the gas processing plants, designing a process for its reduction is necessary. In this study, an accur...
متن کاملModeling and Performance Evaluation of Energy Consumption in S-MAC Protocol Using Generalized Stochastic Petri Nets
One of the features of wireless sensor networks is that the nodes in this network have limited power sources. Therefore, assessment of energy consumption in these networks is very important. What has been common practice has been the use of traditional simulators to evaluate the energy consumption of the nodes in these networks. Simulators often have problems such as fluctuating output values i...
