ESCAPE (Emergency Situation, Context Awareness, Pervasive Environment)
From Autocompwiki
Contents |
Description
Responses to emergency situations, such as earthquakes, floodings, and other natural disasters, are usually conducted in the fields of the disaster (front-end) as well as in the back-ends where strategic decisions are being made. Contextual information about the current and past situation significantly improves the effectivity of these responses. With ESCAPE we introduce a framework for collecting, sharing, and processing of context data, especially in the field of emergency management.
Approach
- Based on open standards, such as SOAP and REST for communication, and XML, XPath, and XQuery for context represenation/querying
- Integeration of front-end and back-end systems
- Integration of multiple sensors
- Accepts any XML-based context model
- Tracing capability through context provenance information
- Multiple levels of context data: situation -> response -> site -> team -> individual
- Target plattforms: Java on PDAs and Laptops
Framework
Each team in the front-end has a team-leader which pushes context data snapshots to the back-end. The communication within the teams is done via SOAP messages & invocations. The communication between the team-leader and the back-end is done via REST.
Architecture
The framework supports kSOAP-based Web services and publishes them via SLP. The functionality of ESCAPE is split into several modules, such as the query engine and the storage facility.

Software
Since 2007 when the first prototype of ESCAPE was introduced in our EuroSSC 2007 paper, many things have been changed. As a result, now we have
- The Web service middleware for ESCAPE (Paper presented in EUROMICRO Conference) is now separated and provided under the RESCUE project.
- A WORKPAD-specific context management system is separated from ESCAPE and is now provided under the COSINE project.
- Current our context model for disaster management (to be opened)
- Libraries for handling context information (to be updated)
- Examples of GIS enriched with disaster context (to be updated)
- QoC (to be updated)
