Implementation of DEVS Based Distributed Network Simulator for Large-Scale Networks

Abstract

In this study, a tool was developed for design and implementation of a new discrete event based distributed simulation for large-scale networks. By using DEVS as a modelling approach, client / server based, scalable, platform-independent, flexible new network modelling and simulation tool called 'D-DEVSNET' was designed and performance analysis were conducted. In order to show the performance of the network simulation tool, D-DEVSNET and the power of the DEVS approach on parallel and distributed applications, some tests were carried out such as the measurement of throughput capability of different sized networks in a certain period of time, the average end-to-end packet delay and the amount of packet loss, consumption of speed and memory. According to the tests that were conducted, D-DEVSNET has been proven a well-scalable and high performing simulation tool.

Design and Implementation of a DEVS-Based Cyber-Attack Simulator for Cyber Security

“…Supporting a hierarchical / modular structure and distributed operation of the DEVS (Discrete Event System Definition) approach provides convenience in modelling complex large-scale systems (consisting of atomic and coupled models). In the parallel and distributed simulation algorithm developed using the DEVS modelling approach, parallelism is provided by using the parallel DEVS atomic and coupled model definition, while the distributed approach is provided with client server-based architecture and this algorithm is used in the development of a DEVS-based network simulation tool [23].…”
