We present the first local approximation schemes for maximum independent set and minimum vertex cover in unit disk graphs. In the graph model we assume that each node knows its geo...
In opportunistic forwarding, a node randomly relays packets to one of its neighbors based on local information, without the knowledge of global topology. Each intermediate node co...
In this paper we examine adaptive time-based web applications (or presentations). These are interactive presentations where time dictates the major structure, and that require int...
The design of interactive software that populates an ambient space is a complex and ad-hoc process with traditional software development approaches. In an ambient space, important ...
In this paper we describe the design and implementation of the VDL Generator, a tool to simplify and automatise the Digital Library development process. In particular, we discuss h...
