Implementation of Application Program Interface of Visitant

Some researches, such as molecular biology, computer graphics, meteorology, and particle physics, are difficult to be completed by a single computer and may spend too much time in experiments. In fact, there are abundant computing resources in the Internet, and most of them are not fully utilized. P2P systems, an increasingly popular technology, can aggregate resources shared from a large number of highly autonomous peers and coordinate these resources among peers. However, current P2P systems can only provide some simple services and functions, including file sharing and instance message. We attempt to integrate two different technologies, P2P platform and mobile agent, to support programmers to develop their customized services and utilize the enormous resources in the Internet.
In this thesis, we continue with the implementation of Visitant system, which is an agent-based structured P2P system and is developed by our laboratory. We implement the functions of Mobility, Communication, and Security issues which are the main issues of mobile agent technology. We also provide a set of APIs and user friendly GUIs for programmers to develop and deploy their mobile agents, and demonstrate two examples to explain how to program customized mobile agents in our system.
