Agent mobility presents distinct challenges not handled by traditional, distributed, communication frameworks. By nature, mobile agents change location over time, making targeted messaging difficult to achieve. Also, a communication infrastructure must handle the case that the agent may be migrating when the message is sent. We have implemented a Distributed Event Messaging System (DEMS) that s...

The paper describes an approach for establishing a mobile agent architecture in the Web. This architecture makes use of currently much discussed interaction principles and the document centric constitution of the Web. It builds out an abstraction layer useful for mobile agent execution and allows realizing various feasible Web applications following the mobile agent principle.

Mobile agent technology is emerging as a new paradigm in the area of distributed and mobile computing. Mobile agents play an important role in the development of active and dynamically managed networks and distributed systems. Mobile agents are the intelligent programs that act autonomously on behalf of a user and can migrate from one host to another host in a network in order to satisfy the re...

This paper introduces the use of mobile agents as the mechanism for policy enforcement in multi-agent multidomain systems. The focus is on the effective application of communication policies in the setup and maintenance of spanning data streams that cross multiple hosts in different domains. We have designed and implemented a mobile agent based framework (FlexFeed) that works in concert with th...

E-commerce on the internet has the ability to produce millions of transactions and a great number of merchants whose supply merchandise over the internet. As a result, it is difficult for entities to roam over every site on the internet and choose the best merchandise to trade. So, in this paper we introduced a mobile trade agent that visit the sites to gather and evaluate the information from ...

A major setback for mobile agent technology is – apart from a frequently cited absence of appropriate security mechanisms – a lack of interoperability between systems for mobile agents, which prevents mobile agents from reaching " critical mass " for widespread application. Interoperability is required where systems of different vendors come into contact with each other. More precisely, two mob...

The agent paradigm is currently attracting much research. A mobile agent is a particular type of agent with the ability to migrate from one host to another where it can resume its execution. In this article we consider security issues that need to be addressed before multi-agent systems in general, and mobile agents in particular, can be a viable solution for a broad range of commercial applica...

Mobile agents are a useful paradigm – other than a useful technology – for the development of complex Internet applications. However, the effective development of mobile agent applications requires suitable models and infrastructures. This paper proposes an organizational approach to the high-level design of mobile agent applications. The idea is to models the Internet as a multiplicity of loca...

In mobile IP networks, a local mobility agent is extended to assist reliable multicast for mobile nodes. Each agent keeps in its buffer all packets that are likely to be requested by any of its mobile nodes. They can provide reliable service by performing a retransmission for the requested packet from its mobile nodes. When a mobile node moves to another subnet, transmission errors tend to happ...
