Wireless users rarely (if ever) benefit from Internet information services thus requiring new type of services and new ways for structuring the needed content. Personalization appears to be the most appropriate solution to this need. It comes into aid by creating personalized portals that directly tones down factors that break up the functionally of the Internet/wireless services when viewed through wireless devices; factors like the click count, user response time and the size of the wireless network traffic. In this paper we present a flexible personalization system tuned for the wireless Internet taking into consideration not only the user profile but the device profile as well. The system utilizes the various characteristics of mobile agents to support flexibility, scalability, modularity and user mobility. We present appropriate, to the wireless environment, metrics and our initial performance evaluation indicates improvement ranging from 33% to, for certain metrics, 60.
