Web service technology is widely applied in building distributed information systems in order to provide flexibility and extensibility. As in the traditional web services, when the number of clients increases, the traffic problems of network may happen and the services may become overloaded. Distributed mobile agent platforms in Web service have become more mature in recent years, and may help reducing the load from Web servers as well as reduce the traffic for overall network. We have proposed an agent-based framework for Web services that is scalable and reliable. The framework uses mobile agents to solve the traffic problem on traditional Web service systems. In this paper, we study the performance of our proposed approach with the focus on response time. We simulate our framework by mathematical models on a network simulator tool. The simulation results showed that our proposed framework has ability to improve performance in comparison with traditional Web service systems.

Nowadays, the peoples are often using the mobile devices to access to data around Internet. The data sources on Internet are growing day by day, and users can be stuck on determining the needed data for them. Also, there doesn't exist any unique system that provides a smart user interface in order to query all necessary data and makes simple on interaction to the end users. This raises a need to visualize Web data and provides data on any kind of mobile devices screens. This paper presents our work on an adaptive Web page layout mechanism for mobile devices. This mechanism can adapt layouts by ranking important data and classifying data.
