Researches On Policy And Mobile Agent Based Ad Hoc Network Management

Because of tremendous application value of Ad Hoc networks, great attentions have been pain to them by many military departments, industry and academia researchers. As a new research area, Ad Hoc networks face many challenges; one of them is network management for Ad Hoc networks. Network management is a technology and method used to monitor, diagnose, test and control communication equipments or transmission systems in networks. Management for Ad Hoc networks is an important condition for ensuring network security, stability, reliability and high-efficiency.Aimed at the prospect and the request of network management for Ad Hoc networks, the thesis studies network management architecture and related issues. After an overall introduction of traditional network management, a comparison of existing network management model for Ad Hoc networks is given first, then on the basis of features of Ad Hoc network such as limited power and imbalances traffic among Ad Hoc nodes, a new policy-based and agent-enabled network management architecture for Ad Hoc networks is proposed using the technologies of policies and mobile agents. The design of each part in the architecture and the management process are explained in details. In addition, the definition of policies of deferent layers and the classification of functions in network management are discussed, which is a supplement to policy-based and agent-enabled network management architecture. According to special request of network management for Ad Hoc networks, the policy information base has been extended in order to manage variables better. Finally, by designing and implementing Ad Hoc network fault management under the architecture, the architecture is proved to have characteristics of flexibility for higher manager and convenience of making full use of methods themselves.
