Abstract :
We present the results of extensive field experiments designed to evaluate the precise relationship between wireless link quality, radio power level, and transmission distance in outdoor embedded deployments. We focus on ZigBee networks, using Tmote Sky nodes, a popular commercial hardware platform for wireless sensor systems. The results are used to develop a piece-wise regression model suitable for pre-deployment link quality prediction. We characterize the contexts in which the model provides high accuracy, and discuss potential threats to validity.
