document: A distributed mobile agent framework for maintaining persistent distance education Mobile agent techniques involve distributed control if communication is required among different types of agents , especially when mobile agents can migrate from station to station . This technique can be implemented in a distributed distance learning environment , which allows students or instructors to login from anywhere to a central server in an education center while still retaining the look-and-feel of personal setups . In this research paper , we propose a distributed agent framework along with its communication messages to facilitate mobile personal agents , which serve three different groups of distance education users : instructors , students , and system administrators . We propose an agent communication framework as well as agent evolution states of mobile agents . The communication architecture and message transmission protocols are illustrated . The system is implemented on the Windows platform to support nomadic accessibility of remote distance learning users . Personal data also migrate with the mobile agents , allowing users to maintain accessibility to some extent even when the Internet connection is temperately disconnected . Using user-friendly personal agents , a distance education platform can include different tools to meet different needs for users
