This paper presents a comprehensive metric to evaluate the link quality of scalable mobile sensor networks to maintain end-to-end communication links. The mobile nodes dynamically reconfigure themselves to maintain reliable end-to-end communication links. The authors present the empirical analysis and results of a link variability study for an indoor environment. All experiments are implemented on a mobile platform called PioMote team. Inspired by the Shannon-Hartley theorem, the analysis of three metrics is proposed, including Received Signal Strength Indicator (RSSI), active throughput, and Packet Loss Rate (PLR).
