    Despite several advantages inherent in mobile-agent-based approaches to network management as compared to traditional SNMP-based approaches, industry is reluctant to adopt the mobile agent paradigm as a replacement for the existing manager-agent model; the management community requires an evolutionary, rather than a revolutionary, use of mobile agents. Furthermore, security for distributed management is a major concern; agent-based management systems inherit the security risks of mobile agents. We have developed a Java-based mobile agent infrastructure for network management that enables the safe integration of mobile agents with the SNMP protocol. The security of the system has been evaluated under agent to agent-platform and agent to agent attacks and has proved trustworthy in the performance of network management tasks

    Mobile Agents (MAs) represent a distributed computing technology that promises to address the scalability problems of centralized network management. A critical issue that will affect the wider adoption of MA paradigm in management applications is the development of MA Platforms (MAPs) expressly oriented to distributed management. However, most of available platforms impose considerable burden on network and system resources and also lack of essential functionality. In this paper, we discuss the design considerations and implementation details of a complete MAP research prototype that sufficiently addresses all the aforementioned issues. Our MAP has been implemented in Java and tailored for network and systems management applications.Comment: 7 pages, 5 figures; Proceedings of the 2006 Conference on Mobile Computing and Wireless Communications (MCWC'2006

    Vehicle Based Intersection Management with Intelligent Agents

    Get PDF
    Signal-based intersection management will change when vehicles with intelligent capability are available in the future. Intelligent agents embedded in vehicle software will be responsible for vehicle control and route guidance. Intersection management can be achieved through the collaboration of these agents, without a centralized control infrastructure. This research focuses on the use of distributed multi-agent systems to provide microscopic adaptive control which might reduce traffic delay and chances of collisions at intersections. A hypothesized Mobile Ad-hoc Network provides communication links to connect the agents.Intelligent Agents, Adaptive Intersection Control

    Recently, a new paradigm has emerged forstructuring and developing distributed network applications inopen distributed and heterogeneous environments. Manyapplication areas, such as electronic commerce, mobilecomputing, network management and information retrieval canbenefit from the application of the Mobile Agent technology. Theexploitation of Mobile Agents offers several peculiar advantages,such as reduction of network latency, asynchronous execution,robust and fault tolerant behavior. Java technology provides aplatform-independent, portable software environment whichmakes it an excellent tool for mobile agent development. MobileAgents are mainly intended to be used for applicationsdistributed over large scale (slow) networks because they allowsaving communication costs by moving computation to the hoston which the target data resides. However, it has not becomepopular due to some problems such as security. In this paper, wepresent a distributed network architecture based on the MobileAgent approach. A network of communicating servers each ofwhich support multiple clients is our goal. We also propose asecurity approach for mobile agents, which protect critical dataof mobile agents from malicious attacks, by using cryptographictechniques. We implement a bank service application to be testedon our mobile agent framework. The results suggest that fornetworks with high latency, Mobile Agents may provideimprovements over more conventional client-server systems

    The explosive growth of the Internet and the continued dramatic increase for all wireless services are fueling the demand for increased capacity, data rates, support of multimedia services, and support for different Quality of Services (QoS) requirements for different classes of services. Furthermore future communication networks will be strongly characterized by heterogeneity. In order to meet the objectives of instant adaptability to the users\u27 requirements and of interoperability and seamless operation within the heterogeneous networking environments, flexibility in terms of network and resource management will be a key design issue. The new emerging technology of mobile agent (MA) has arisen in the distributed programming field as a potential flexible way of managing resources of a distributed system, and is a challenging opportunity for delivering more flexible services and dealing with network programmability. This dissertation mainly focuses on: a) the design of models that provide a generic framework for the evaluation and analysis of the performance and tradeoffs of the mobile agent management paradigm; b) the development of MA based resource and network management applications. First, in order to demonstrate the use and benefits of the mobile agent based management paradigm in the network and resource management process, a commercial application of a multioperator network is introduced, and the use of agents to provide the underlying framework and structure for its implementation and deployment is investigated. Then, a general analytical model and framework for the evaluation of various network management paradigms is introduced and discussed. It is also illustrated how the developed analytical framework can be used to quantitatively evaluate the performances and tradeoffs in the various computing paradigms. Furthermore, the design tradeoffs for choosing the MA based management paradigm to develop a flexible resource management scheme in wireless networks is discussed and evaluated. The integration of an advanced bandwidth reservation mechanism with a bandwidth reconfiguration based call admission control strategy is also proposed. A framework based on the technology of mobile agents, is introduced for the efficient implementation of the proposed integrated resource and QoS management, while the achievable performance of the overall proposed management scheme is evaluated via modeling and simulation. Finally the use of a distributed cooperative scheme among the mobile agents that can be applied in the future wireless networks is proposed and demonstrated, to improve the energy consumption for the routine management processes of mobile terminals, by adopting the peer-to-peer communication concept of wireless ad-hoc networks. The performance evaluation process and the corresponding numerical results demonstrate the significant system energy savings, while several design issues and tradeoffs of the proposed scheme, such as the fairness of the mobile agents involved in the management activity, are discussed and evaluated

    [[abstract]]Mobile agents refer to self-contained and identifiable computer programs that can migrate along the network and can act on behalf of the user or other agents. Mobile agents often work on heterogeneous network and operating system environment. Therefore, an integrated logical interface to access physical structure via mobile agent application is become more and more urgent. In this paper, we proposed a tracking and persistent agent-based mobility management system in the case of distance learning. The main purpose of our system is addressed to achieve the universal access objective. In order to let the whole mobility management system full play, we encapsulated the utility tools to be a role-setting object. The role-setting object is an application-driven component, which can provide customization benefits for user and matching the user’s demands. These integrated technologies are sufficient in distance learning (virtual university) environment.[[notice]]補正完
