When there are multiple queries posed to the resourceconstrained wireless sensor network, it is critical to process them efficiently. In this paper, we propose a Two-Tier Multipl...
DHTs are scalable, self-organizing, and adaptive to underlying topology changes, thus being a promising infrastructure for realizing efficient Web service discovery. Range queries...
In this paper we study in-network query processing in disconnected mobile environments, where both ad-hoc communication and infrastructure communication are available. Depending o...
On the Internet, the limited query-processing capabilities of sources make answering even the simplest queries challenging. In this paper, we present a scheme called GenCompact fo...
An important problem in geometric compression is to find succinct representations (encoding schemes) for the conectivity of polygonal meshes. In this note, we show that the encod...
