Traditional spatial information systems hold only a single state of the ‘real world’. However, geographic phenomena have not only static but dynamic characteristics. The work d...
Collaborative beamforming has been recently introduced in the context of wireless sensor networks (WSNs) to increase the transmission range of individual sensor nodes. In this pap...
— Fuzzy clustering methods have been widely used in many applications. These methods, including fuzzy k-means and Expectation Maximization, allow an object to be assigned to mult...
Data broadcasting is well known for its excellent scalability. Multi-dimensional range queries, such as spatial range queries of geographical information for location dependent se...
In the future, intelligent sensors will connected through networks, each node have its own autonomy, heterogeneity, and under dynamic environments. We call these systems as a Hete...
