This book revolves around the application of the wireless sensor networks for monitoring the fitness levels of the sports players in real time. A wireless sensor platform is developed to enable rapid proto-typing for such applications. The main focus of this work is the design and implementation of a time-sharing protocol,considering the application specific requirements like huge volume of raw data from that of say, a 3-axis accelerometer and covering the entire play-field with the tiny nodes. Real world tests are conducted with multiple nodes in various environments to validate the...
