The focus of this study in progress is based on a non-GPS navigation technique which can be used in an environment without any infrastructure. Our proposed system combines a Wireless Body Area Network (WBAN) consisting of different sensors with Complex Event Processing (CEP). For the identification of complex events for independent navigation three use cases are provided.

The analysis of physical human activities is essential in order to detect falls in real time and to ensure rapid assistance by the emergency service, especially for people who are exposed to a high risk of falling in everyday life due to dangerous working conditions or certain illnesses. In this scope, we present an ongoing development of a portable motion analysis system that performs continuous movement monitoring regardless of the environment. The system is a real time distributed application consisting of the portable sensor network and an analysis unit based on Stream Processing and Complex Event Processing.
