Abstract:
In this paper we introduce a distributed emulator for a pedestrian tracking system using active tags that is currently being developed by the authors. The emulator works on StarBED, which is a network testbed consisting of hundreds of PCs connected to each other by Ethernet. The three major components of the emulator (the processor emulator of the active tag micro-controller, RUNE, and QOMET) are all implemented on StarBED. We present the structure of the emulator, how it functions, and the results from the emulation of the pedestrian tracking system. The emulator accomplished quite accurate emulation of ubiquitous network systems with the technique of emulation. We found several issues originated from active tag’s firmware or protocol by applying the emulator to the emulation of the tracking system. We confirmed the results obtained by running tests corresponding to a real-world experiment.
