openWNS - a simulation platform for IMT-advanced systems

Abstract

The open source wireless network simulator (openWNS) is presented. It has been released in January 2009 as open source software. openWNS is a dynamic event driven system level simulation platform useful for investigation of dynamic protocol behaviour in multi-cellular mobile radio network scenarios with detailed signal interference modelling. The platform follows a modular design down to atomic protocol building blocks, making possible to rapidly modify and extend a protocol stack implemented. openWNS includes models from physical to application layer and is supported by a large number of Unit Tests. The tool has been used for IMT-Advanced evaluation within the European WINNER+ evaluation group. Copyright © 2010 John Wiley & Sons, Ltd.
