Design and Implementation of Visualizers for TinyOS

TinyOS is a popular event driven operating system for wireless sensor network (WSN). However TinyOS 2.x framework lacks proper visualization approach for simulator TOSSIM and also for real-time network. In this paper we present approaches to add support for two visualizers in TinyOS framework. One such graphical addition is for simulator TOSSIM and another is for real- time network. The main contributions of this paper are 1) Visualizer for TOSSIM 2) 3D visualizer for real time data collection in WSN.
