The mobile agent paradigm has been proposed as a promising solution to facilitate distributed computing over open and heterogeneous networks. Mobility, autonomy, and intelligence are identified as key features of mobile agent systems and enabling characteristics for the next-generation smart electronic commerce on the Internet. However, security-related issues, especially integrity protection i...

Agent technology is rapidly emerging as a powerful computing paradigm to cope with the complexity in dynamic distributed systems, such as traffic control and management systems. However, while a number of agent-based traffic control and management systems have been proposed and the multi-agent systems have been studied, to the best of our knowledge, the mobile agent technology has not been appl...

Mobile agents have attracted considerable interest in recent years. In the context of mobile agents, fault tolerance is crucial to enable the integration of mobile agent technology into today’s business applications. This article identifies two important properties for fault-tolerant mobile agent execution: nonblocking and exactly-once. Nonblocking ensures that the agent execution can proceed d...

A fundamental issue in the development of mobile agent systems is how to provide support for agent applications reliability. For some agent applications areas (such as electronic commerce or workflow) it is fundamental that mobile agent executions are fault tolerant and exhibit transactional semantics or that groups of mobile agents can coordinate their activities with the use of a reliable com...

Mobile agent technology is promising for e-commerce and distributed computing applications due to its properties of mobility and autonomy. One of the most security-sensitive tasks a mobile agent is expected to perform is signing digital signatures on a remote untrustworthy service host that is beyond the control of the agent host. This service host may treat the mobile agents unfairly, i.e. acc...

Agent technology is a novel approach for the development of distributed systems. In particular, mobile agents can provide much greater flexibility and robustness than the traditional distributed system methodologies since they provide mobility from platform to platform. Thus, they form a vast area of research. One key problem faced by the mobile agent systems is security. A migrating agent can ...

A mobile agent is a promising area in distributed systems. It is a new technology for computers to communicate. Despite the multiple benefits of the mobile agent, but there are several obstacles to its spread. The mobile agent protection is one of these obstacles. In this paper a new mechanism has been proposed to protect mobile. The mechanism is called Partial-Mobility Mechanism (PMM). The mai...

 In this paper, we present DTP (Distributed Task Plan), a model to depict distributed tasks for executions by mobile agents. DTP is composed of autonomous primitives and can generate the autonomous workflow when a mobile agent executes it. DTP provides mobile agents with navigational and computational autonomies when transporting through the underlying computational network. A mobile agent pla...

A new definition and realization of mobile agent was advanced: task-description-based mobile agent, which is a kind of data package describing the tasks needed to perform on the agent platforms. A secure mobile agent system building on this kind of mobile agent was proposed. By way of using Proxy/Manage Agency to create and dispatch agents, Java 2 security model to protect local resources and t...

This paper presents a possible roadmap for what we call a “Sweeper-Agent”: an environment-friendly agents-based mobile technique, which is carried out within the activities of BlueAgents, a newly-formed research project focusing on the integration of mobile Bluetooth communications and Agent-based applications. We foresee an architecture of a service management technique that would increase the...
