Sensing the state of the environment is an important source for context-aware applications. Several approaches exist to provide sensor information to mobile application nodes. As ...
We assume a sensor network with data-centric storage, where sensor data is stored within the sensor network and ad hoc queries are disseminated and processed inside the network. I...

Abstract. A crucial issue in the management of sensor networks is the continuous monitoring of residual energy level of the sensors in the network. In this paper, we propose a hier...
The term wireless sensor network is applied broadly to a range of significantly different networking environments. On the other hand there exists a substantial body of research on...
We propose a hybrid model to alleviate the notorious problem of premature battery depletion in sensor networks: in a first stage, simple sensors are deployed over an area of inter...
