This paper is concerned with a problem in information organization and retrieval within Web communities. Most work in this domain is focused on reputation-based systems which exploit the experience gathered by previous users in order to evaluate resources at the community level. The current research focuses on a slightly different approach: a personalized evaluation system whose goal is to build a...
We consider fair sharing of network resources over a period of time between offline and interactive users. The former value total transferred volume while the latter have time-dependent valuations for instantaneous bandwidth. Following the work of Kelly on fair bandwidth sharing, we express the system optimum as an equilibrium of traditional congestion control taking place in a fast timescale and...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
