Wireless Communications Test Bed Overview and Monitoring Architecture

This presentation outlines the Wireless Communications Test Bed developed at the University of Colorado. It discusses the high-level architecture, including the layout of ad hoc radio networks, fixed sites, mobile nodes, and data gathering capabilities. Each network node collects vital data such as GPS position and packet statistics, which are periodically sent to the test bed gateway. The gateway serves as a critical data collection point for monitoring and analysis, with remote access for live monitoring. This initiative aims to enhance remote accessibility and improve wireless communication protocols.
