Ubiquitous Mobile Agent System in a P 2 P-Network

The vision of ubiquitous computing projects a multitude of computers surrounding people. The ubiquitous environment is to support people in their everyday life in an inconspicuous and unobtrusive way. This requires that information of the person and her preferences, liking, and habits are available in the ubiquitous system. Since mobility is in the nature of people the system has to ensure that the information moves with the persons. One possibility is to store a mobile virtual reflection of the person in the ubiquitous environment. This reflection should follow people in the virtual world. The paradigm of the mobile agents ideally matches here to represent mobile objects by mobile virtual objects. This paper introduces a ubiquitous mobile agent system called UbiMAS that is used to accompany and lead persons in an office building with smart doorplates. The agent system is based on an ubiquitous middleware which uses a JXTA peer-to-peer network as communication
