Wireless Sensor Networks raise the interest of different business domains, including public security [5]. The ability of WSNs to monitor and control physical environments such as football stadiums makes them very attractive. The integration of WSNs into Command and Control (C2) systems aims at avoiding catastrophes such as the Heysel Stadium disaster [16].(More)
In an emergency situation failure to respond in a timely manner poses a significant threat. Data needed for timely response comes from various sources and sensors. These individual data streams when viewed in isolation may appear irrelevant, however, when analyzed collectively may identify potential threats. An effective and timely response also requires(More)
In the last few years, a number of spatial and spatio-temporal access control models have been developed especially in the framework of pervasive computing and location-aware applications. Yet, how useful and effective those models are in real applications is still to be proved. The goal of this panel is to discuss access control requirements in mobile(More)

Coordination between different organizations in dynamic situations, such as a disaster response, is challenging. Organizations are autonomous and coordinate the situation from their point of view. There is no central authority to coordinate all operations. To coordinate their actions, organizations need to exchange information on what they are doing.(More)
In this work we present a general framework for process-oriented coordination and collaboration in humanitarian operations. Process management has been proven useful in many business domains, but humanitarian operations and disaster response management in general require different process management approaches. Related work has only recently introduced(More)
We consider in this paper that mobile devices should be seen as active objects communicating through web technologies, in a sense that they can both receive and send information. Therefore, following our introduction motivating our work, we propose a lightweight architecture that enables object orientation through web technologies. This architecture is(More)
Embedded systems are predicted to occupy a growing place within business activities. But the term covers a wide range of devices which has not yet been seen with a common approach. This paper deals with how we can bridge the gap between intelligent devices and an enterprise resources planning (ERP) system like SAP R/3. We present a clustering of existing(More)
One problem during an emergency for the teams in the field and the command center is to get an overview about who is doing what and how it is related to other activities. Current approaches for developing such an overview, for example, email, phone or radio are message-based and do not highlight dependencies between activities, do not support a(More)
