A new service discovery scheme adapting to user behavior for ubiquitous computing

Abstract

Discovering primary services requested by users is a very difficult but crucial task in networked system, especially in ubiquitous computing system. The service discovery also has to be an accurate, fast, and stable operation. The typical lookup services such as SLP, Jini, and UPnP focus on either wired networks or particular networks. In this paper, thus, we propose a new service discovery algorithm using service agents adapted to user behavior. We compare the proposed algorithm with the DEAPspace algorithm using real experiment. It reveals that the proposed scheme offers services to the users seamlessly and accurately as much as DEAPspace, while the number of packets used is about half of it. © Springer-Verlag Berlin Heidelberg 2005.
