While most other positioning systems are limited to specific scenarios and technologies our system provides means to incorporate any available wireless networking technology. Currently, MagicMap supports WLAN, RFID, and ZigBee as wireless technologies for positioning and Linux, Windows, and Windows CE as platforms. Position calculation and exchange is based on a cooperative approach allowing an open internet community to share the required data.

We focus on an open and extendable distributed robotics system, which in contrast to most existing proprietary robotics systems, supports cost-effective integration and assembly of components while providing dependable communication and coordination. To demonstrate feasibility we have developed the CERO Framework for ad hoc cooperation in robots communities employing a service-oriented architecture with the main building blocks: ad hoc networking for different wireless technologies (e.g., Bluetooth, WLAN, or 433 MHz radio communication), a protocol for interconnecting development board and actuators, and a CE.NET based software framework supporting complex movements, consensus protocols, cooperation, and positioning. It offers high-level interfaces for programming complex tasks in cooperative robotics. We also present an overview of intended applications.

T1 - Towards a Global Real-Time Enterprise T2 - Emerging Spatial Information Systems and Applications N2 - Frictionless interoperation of business processes even across enterprise boundaries, complete up-to-date view of the overall status, and full remote control over the business parameters for individuals in charge – this is the holy grail of a “global real-time enterprise”. Yet a vision, a number of enabling technologies brought us closer to accomplishing the challenges: Sensing the position of mobile objects and processes status, distributing the status information with “zero latency”, discovering it according to specific demands across organisation boundaries, providing and securing uniform service-oriented access to all kinds of entities ranging from smart items to business processes, and aggregating the overwhelming variety of elementary services to form high-value composite services. In this chapter, we overview the enabling technologies that drive the development and further discuss market factors, security and privacy concerns, and standardization processes that have to be considered. Then we propose our SEMALON approach – the SEMAntic LOcation Network – intended as a basic infrastructure for discovery and composition of location based services. Finally we describe our experiences from a case study implementation – the NOMADS Campus – which is a distributed spatial information system for our campus at Humboldt University Berlin.

However, past experiences have shown interoperability limitations in practice mainly due to information asymmetries on the Web Services markets. This Paper describes a service-oriented architecture for building Dynamic Value Webs in mobile environments using adaptive Location-Based Services. Our concept addresses the following three predominant difficulties: (1) service adaptivity to changing conditions in mobile environments, (2) interoperability including higher levels of semantics, and (3) assuring trustworthiness to all affected parties.
