Context-Aware Sensors [chapter]

Eiman Elnahrawy, Badri Nath
2004 Lecture Notes in Computer Science  
It enables the sensors to locally predict their current readings based on their own past readings and the current readings of their neighbors. In this paper, we introduce context-aware sensors.  ...  Wireless sensor networks typically consist of a large number of sensor nodes embedded in a physical space.  ...  In other words, sensors are aware of their context (the neighborhood and history).  ...

Context-aware management for sensor networks

Frieder Ganz, Payam Barnaghi, Francois Carrez, Klaus Moessner
2011 Proceedings of the 5th International Conference on Communication System Software and Middleware - COMSWARE '11  
In this paper, we describe a middleware architecture that uses context information of sensors to supply a plug-and-play gateway and resource management framework for heterogeneous sensor networks.  ...  Based on the context information such as battery status, routing information, location and radio signal strength the gateway will configure and maintain the sensor network.  ...  CONTEXT-AWARENESS IN SENSOR NETWORKS The sensor node context is the information which is not related to the real sensing operation and information.  ...

Context-aware applications using personal sensors

Julien Subercaze, Pierre Maret, Ngoc Minh Dang, Ken Sasaki
2007 Proceedings of the Second International Conference on Body Area Networks BodyNets  
Context-aware applications require the development of convenient frameworks. Effective mobility requires that mobile applications can integrate new sensors or new types of information.  ...  We describe in this article an agent-based framework supporting sensors' data fusion and context-aware information exchanges. An ontology-based representation of data is used.  ...  Exchanges are done using Virtual Knowledge Communities (VKC); Sensor-based Context Agent We consider that a context-aware application is a complex decision maker.  ...
