We explain basic features of an emerging area called Intelligent Environments. We give a short overview on how it has developed, what is the current state of the art and what are the challenges laying ahead. The aim of the article is to make aware the Computer Science community of this new development, the differences with previous dominant paradigms and(More)
This paper presents a framework for active networks. The framework is unique among other existing active networks in being based on mobile agents. It allows protocols to be implemented within mobile agents and dynamically deployed at end systems. Moreover , it can dispatch networked applications, including client/server programs built on TCP/IP, to remote(More)
This paper presents a new framework for constructing mobile agents. The framework introduces the notion of agent hierarchy and inter-agent migration and thus allows a group of mobile agents to be dynamically assembled into a single mobile agent. It provides a powerful method to construct a distributed application, in particular a large-scale mobile(More)
This paper presents a framework for reusable mobile agents for network management in the sense that they are independent of either particular networks or applications. The framework enables a mobile agent to be composed from two layered components, which are mobile agents. The former is a carrier of the latter over particular networks independent of any(More)

— Mobile agents can migrate among nodes to perform a set of management tasks at each of the visited nodes. Existing mobile agent-based network management systems often assume that their mobile agents are designed to work in particular networks to raise the efficiency of agent migration among multiple nodes. Unfortunately, such mobile agents cannot be reused(More)
—We present a framework for testing applications for mobile computing devices. When a device is moved into and attached to a new network, the proper functioning of applications running on the device often depends on the resources and services provided locally in the current network. This framework provides an application-level emulator for mobile computing(More)

This paper presents a world model for location-aware and user-aware services in ubiquitous computing environments. It can be dynamically organized like a tree based on geographical containment, such as user-room-floor-building, and each node in the tree can be constructed as an executable software component. The model is unique to existing approaches(More)
