Open Source Simulator & Visualizer for WSNs

NetTopo is an open source research-oriented simulator & visualizer designed to test and validate algorithms for wireless sensor networks. The goal of NetTopo is to build a sensor network simulation and visualization tool that gives users extraordinary flexibility to simulate their own algorithms and is a compelling replacement of commercial simulator focusing on visualization of the communication in the real wireless sensor network test bed. NetTopo with the latest version has the following features: * Customizable sensor network topology layout. * Configurable sensor nodes with user-defined attributes. * Easy extensibility to simulate user-defined algorithms. * Specific step-by-step simulation comparison between GPSR and TPGF. * File-based function facilitating users to save and retrieve their simulating process. * Graphical user interface with local operating system look and feel. * (Support for XML import and export.) * Platform independent (written in Java). * (Integration and virtualization of the real wireless sensor network test bed.) * (Support for 2D and 3D) Website of NetTopo: http://www.semanticreality.org/nettopo/index.htm For download from Sourceforge: http://sourceforge.net/scm/?type=cvs&group_id=224160
