| 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.
