Future areas of application for mobile agents technology are open, distributed and decentralized networks, where Mobile Agents autonomously perform tasks on behalf of their principals . In this paper, we address the conceptual design of payments for and between Mobile Agents, particularly against the background of the Malicious Host Problem. We analyze the requirements on payment systems for Mo...

In the last years, mobile agents are gaining great attention as a new concept for developing and implementing mobile and distributed applications. However, very little work has taken place in defining concepts and notations to model mobile agents. In this paper, we present an approach to model and to implement mobile agents. This approach is materialized by a UML notation, called MA-UML for mod...

In this paper we present the design and the implementation of Mobile-C, an IEEE Foundation for Intelligent Physical Agents (FIPA) compliant agent platform for mobile C/C++ agents. Such compliance ensures the interoperability between a Mobile-C agent and other agents from heterogeneous FIPA compliant mobile agent platforms. Also, the Mobile-C library was designed to support synchronization in or...

Growing recognition of the benefits of mobile agents in distributed systems, such as military C4ISR, has led to a proliferation of mobile agent systems. However, incompatibilities between proprietary systems prevent the greater potential benefits of ubiquitous mobile agent computing. In particular, agents cannot migrate to a host that runs a different mobile-agent system. Prior approaches to in...

Mobile agent systems provide new perspectives for distributed e-commerce applications. These applications may present specific restrictions, making mobile agent systems a feasible solution. Even so, mobile agents present some security related problems. An important one is resource access control. The ability for mobile agents to provide a simple, scalable, flexible, and secure access control sy...

Mobile agent has developed for decade, and widely implemented in distribute computation. However, traditional mobile agents including strongmigration and weak-migration mobile agents still have some weakness. With the fabric of Grid virtual organization architecture, the mobile agent has gain great advantage comparing to those old mobile agents system. In this paper, a novel formalized mobile a...

In the emerging world, in a resource constrained network like mobile ad hoc network, the mobile agent is becoming a favorable option for creating applications like service discovery, network discovery, automatic network reconfiguration etc. due to its astonishing features like autonomy and mobility. The joint venture of the two technologies mobile agent and mobile ad hoc network is contributing...

Mobile Agents is a new paradigm for distributed computing where security is very essential to the acceptance of this paradigm in a large scale distributed environment. In this paper, we propose protection mechanisms for mobile agents. In these mechanisms, the authentication of mobile agents and the access control to the system resources are controlled by the mobile-agents platform. Each agent d...

Two major approaches have been proposed to route messages transparently to mobile agents. Either messages may be sent to a fixed “home agent”, which forwards them to mobile agents, or messages may follow forwarding pointers left by mobile agents. A home agent appears as a single point of failure: when it exhibits a failure, it becomes impossible to track mobile agents or to route messages to th...

Agents have to be both autonomous and mobile in many WWW applications such as mobile computing. In this paper, we present ASS (Active State Space), a model of distributed supporting environments for autonomous mobile agents. We use ASS as a mediate media, which maps heterogeneous resources and knowledge representations into homogeneous virtual resources. In this manner, ASS is able to deal with...
