Research And Realization Of Wireless Active Networks Accounting System

Active Network is a intelligentzed network in which the node can disposal customized programme. Along with its development in many applied field, how to apply Active Network into wireless network accounting become a very banausic part of Active Network research. Making use of Active Network technology in wireless network accounting can help wireless user choose different combination of services depend on the price, and it can also fulfills ISPs' demand. This application brings challenge to our research of technology correlatived. First we'll set up model, then resolve detail problems like security, executive environment and so on.In this paper, we propose our own resolvent of active distributed accounting on frame level, designing Active Distributed Accounting Fra-me for Wireless Network and Node Security Model in Active Distributed Accounting. First, to accommodate the future wireless network accounting requirements, we propose an Active Distributed Accounting Frame for Wireless Network which use new technology as Mobile IP, Mobile Agent and so on. In this frame, I introduce the notion of route selecting base on price, which give users activeness of choosing service and vindicate their behalf. Then we prove the frame's practicability, distributing and scalable with an antitype experiment based on this accounting frame compiled by DELPHI 7.0 language. Secondly, we propose an Node Security Model in Active Distributed Accounting to solve the security problem of this frame. We focus on the access authorization policy based on role and Encryption of the accounting data in active node, especially we improve on traditional "negotiatory" secret key distribute protocol "GDH.2" to the latter. Thirdly, we discuss the problem in active network experiment—interoperability of EEs, proposing ANSP model, transparent socketing all kinds of EEs in an experiment network base on J-sim and compareing their network capability test.In the end, we review the whole paper above, summarizing several new thought an idea this paper proposed, but indicating many drawbacks that can't be avoid, finally pointing out that Active Distributed Accounting Frame for Wireless Network will get more attention along with development of active network technology.
