Mobile agents are an emerging technology attracting interest from the fields of distributed systems, information retrieval, electronic commerce and artificial intelligence. We present an infrastructure for mobile agents based on the Hypertext Transfer Protocol (HTTP) which provides for agent mobility across heterogeneous networks as well as communications… (More)
An open problem in mobile agent research is the interaction between agents in different 'worlds'. In this paper, we survey various approaches to agent interaction and discuss the interoperation between Telescript and ffMAIN agents through the use of the Hypertext Transfer Protocol (HTTP) and the shared information space provided by ffMAIN.
Mobile agents constitute a new approach to the architecture and implementation of distributed systems. A mobile agent is a program with a persistent identity which moves around a network and can communicate with its environment and other agents. Possible applications for mobile agents include network management, information retrieval, distributed… (More)
Future systems for mobile communications will have many users who can access a large number of services from various changing locations. Such systems need adequate data management technology to fulfill the expectations of users and providers. A management system for user-related data in mobile communications must support near real-time access to… (More)
Future wireless communications systems will have to rely on a decentralized, scalable and redundant database infrastructure supporting flexible and evolving management strategies at different levels. In this paper, we claim that mobile agents are a promising approach to implementing such strategies in an efficient and modular fashion.
Application-level scripting is a powerful method for structuring software. This paper introduces TkDVI, a T E X DVI previewer based on the Tcl/Tk scripting language and graphics toolkit. After a brief introduction to Tcl/Tk, we present the design and major components of the previewer, pointing out the specific advantages gained by using Tcl/Tk. A number of… (More)
