We pose the question: how do we efficiently evaluate a join operator, distributed over a heterogeneous network? Our objective here is to optimize the delay of output tuples. We di...
In the case of large-scale distributed environments such as the Internet, users are interested in monitoring changes to a particular web page (XML or HTML). There are many instanc...
Abstract— Sensor network data has both historical and realtime value. Making historical sensor data useful, in particular, requires storage, naming, and indexing. Sensor data pre...
We propose a novel approach for recognizing hand gestures by analyzing the data streams generated by the sensors attached to the human hands. We utilize the concept of ‘range of...
Many location-based applications require constant monitoring of k-nearest neighbor (k-NN) queries over moving objects within a geographic area. Existing approaches to this problem...
