Abstract:

The tracking of objects and humans has recently received a lot of attention as a tool to improve business processes, occupational and public safety. In wireless sensor networks location information is needed to put sensor readings into geographical context. In industrial environments wireless sensor networks can facilitate deployment of tracking applications as they can establish a standalone communication infrastructure (so called mesh networks). Nevertheless the communication infrastructure and thus the tracking applications rely on radio transmission; therefore well-known problems from other radio-based tracking solutions (e.g., WLAN)--like ambiguous locations and neighboring-room problem--may occur. We propose a two layered deployment scheme for wireless sensor networks to overcome these limitations. It consists of a robust communication layer and a flexible location layer, which enable per-room accuracy. Such accuracy is sufficient for many types of tracking applications.
