The explosive growth of the Internet has fuelled the creation of new and exciting information services. Most of the current technology has been de- signed for desktop and larger computers with medium to high bandwidth and generally reliable data networks. On the other hand, hand-held wireless devices provide a much more constrained and poor computing environment compared to desktop computers. That is why wireless users rarely (if ever) benefit from Internet information services. Yet the trend and interest for wireless services is growing with fast pace. Personalization comes into aid by directly toning down factors that break up the functionally of the Internet 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 per- sonalization system tuned for the wireless Internet. The system utilizes the various characteristics of mobile agents to support flexibility, scalability, modularity and user mobility.
