U-Deal: A Decentralized Trail-aware Model for Business Opportunities Identification

This article presents the U-Deal, a decentralized and multi-agent ubiquitous commerce model, that describes a peer-to-peer context aware system, with a distributed context history (trail) engine and a dynamic profile generator. The aim of the model is to provide an automatic deal opportunity recommendation, based on user profile, preferences and activities history in a peer-to-peer environment. In this text, we present a system specification and a prototype, including two simulated u-commerce scenarios.
