Routing strategy is one of the most important aspects in a mobile agent system, which is a complex combinatorial problem. Most of current mobile agent systems adopt static routing strategies, which don’t consider dynamic network status and host status. This is a hinder to the performance and autonomy of mobile agents. Ant Algorithm is good at solving such kind of problems. After analyzing exist...

In this paper we argue that the agent paradigm offers promising techniques for dealing with the challenges of building intelligent mobile services. We present Agent Oriented Software Engineering as a solution for the problems in designing a new generation of mobile services. To illustrate our position, we present a brief agent-oriented analysis of a mobile commerce scenario.

This paper first introduces the Concordia, including its principle, its components and its features. Then we focus our emphasis on agent collaboration and the facilities that Concordia provides us, which are the most important parts in concordia. In the end, the concordia’s merits and drawbacks are analyzed briefly.

Mobile agents (MAs) are increasingly gaining attention in both research and the commercial world. In terms of software, mobile agents are active, autonomous software objects containing both computational logic and state information. Agent technology has many forms such as station, mobile and multi-agent, etc. In this paper, MAs will be addressed as tools for mobile computing. MAs have been used...

Security is a fundamental precondition for the acceptance of mobile agent systems. In this paper we present a mobile agent structure which supports authentication, security management and access control for mobile agents.

A automatic human tracking system using mobile agent technology is realized because a mobile agent moves in accordance with a migration of a target person. In this paper, we propose a method for determining the neighbor node in consideration of the imaging range of cameras. Keywords—Human tracking, Mobile agent, Pan/Tilt/Zoom, Neighbor relation.

A mobile agent is a software code with mobility which can be move from a computer into another computers through network. The mobile agent paradigm provides many benefits in developments of distributed application at the same time introduce new requirements for security issues with these systems. In this article we present a solution for protection agent from other agents attacks with loging pa...

Mobile agent technology has become a new paradigm for distributed real-time systems because of their inherent advantages. In any distributed system, along with other issues, survivability and fault tolerance are vital issues for deploying mobile-agent systems. E-business becoming a prominent domain for deploying agent technology, it also faces reliability problems due to the failure of agent pl...

IP Multicast is an eecient mechanism of delivering a large amount of data to a group of members over the Internet. Link sharing is achieved by a multicast tree that connects all group members. Mobile IP is the proposed standard for IP mobility support and provides two schemes for mobile hosts to receive multicast packets, either through tunneling from the home agent (called home subscription) o...

This paper presents an approach for modeling and modelchecking a mobile agent system specified by LAM, which is a two-layer formal method for characterizing logical agent mobility using Predicate/Transition (PrT) nets. Based on the transformation of PrT nets into input programs of the model checker SPIN, we model check a variety of properties with respect to agents, logical agent mobility, agen...
