This article presents the research work that exploits using XML (Extensible Markup Language) to represent different types of information in mobile agent systems, including agent communication messages, mobile agent messages, and other system information. The goal of the research is to build a programmable information base in mobile agent systems through XML representations. The research not onl...

Mobile IP is the proposed standard for IP mobility support. A mobile node registers its current location with its home agent when it moves across IP subnets in a foreign network. When a mobile node is far away from home, registration with its home agent can cause a long handoo delay. We have extended Mobile IP with routing agents. The routing agent of a mobile node serves as the current locatio...

This paper presents a framework for mobile agents. The framework is unique among other mobile agent systems in structuring mobile agents hierarchically. The framework provides the notion of agent hierarchy, in which each mobile agent can be a container of other mobile agents. We construct a prototype implementation of this framework. It is built on the Java language and mobile agents are given ...

Mobile IP is the proposed standard of IP based protocol for mobile internetworking. Mobile nodes register with their home agents for location updates as they roam across IP subnets. IP datagrams for mobile nodes are routed rst to their home agents before being tunneled to mobile nodes through their current foreign agents. This paper investigates dynamic location control for mobile nodes and int...

Mobile agent plays an important role in developing applications of open, distributed and mixed environments, such as the internet. Mobile agent or mobile software agent is piece of software that can operate autonomously to accomplish user assigned task. To explain more, mobile agent is the process which can migrate to hosts autonomously. As an agent travels to do execution in different environm...

The effects of mobile agent technologies are expected in mobile environment. However, the problem of security exists. Malicious host may tampers with a mobile agent. In this paper, we propose a system which records a migration route of a mobile agent in secure. Moreover our proposal corresponds, when the mobile agent is terminated unjustly.

Fault tolerance is fundamental to the further development of mobile agent applications. In the context of mobile agents, fault-tolerance prevents a partial or complete loss of the agent, i.e., it ensures that the agent arrives at its destination. In this paper, we present FATOMAS, a Java-based fault-tolerant mobile agent system based on an algorithm presented in an earlier paper. In contrary to...

Although mobile agents and their supporting infrastructures have been extensively developed, it is still an emerging technology. A wider acceptance of mobile agents would be facilitated with the exploitation of suitable methodologies and tools which fully support their development lifecycle. This paper proposes a Statecharts-based development process for mobile agents, which allows for a seamle...

Mobile agent technology is a new computing paradigm appropriate for distributed computing environment. To eliminate various security issues and its corresponding solutions available in existing mobile agent systems like free roaming mobile agent, an alternative model has been developed called as MHMA (Matrix Hop Mobile System) system. In MHMA, the offer (offer means data) collected from the rem...
