Applying User Profiles in Transient Peer-to-Peer Environment

Abstract

Semantic data is widely used in order to increase the performance of peer-to-peer information retrieval networks. The most efficient approaches construct user profiles in order to describe the fields of interest of the users and to shape a semantic overlay network. However, the characteristics of mobile devices and the behavior of wireless peer-to-peer users require the consideration of the applied algorithms and protocols when applying them in such environment. In this paper we describe our experiments with a special mobile Gnutella client that collected information on the mobile user behavior, together with the other distinctiveness of the mobile environment. We also propose an appropriate utilization of user profiles in transient peer-to-peer systems.
