A flexible architecture for a robust indoor navigation support device for firefighters

In harsh indoor environments like in a firefighter operation location technologies would help to reduce casualties. However, exact indoor localization is still a research topic. We aim to create a wireless sensor network based ad hoc system which builds on the existing navigational skills of firefighters. Allowing them to shape the system as it best fits the actual operation will enhance efficiency at affordable costs. Such a system could provide the advantages of a fixed infrastructure independent of the place of action. In this paper we first analyze the architectural requirements of such a system. Second, we present a corresponding three layered system design which is comprised of network, data management and data storage layer. Third, an implementation of the architecture is presented. Fourth, a prototype implementation of the system and finally, a report on the system evaluation is given. The designed architecture is a promising approach towards a robust and flexible indoor navigation support device for firefighters.
