Mobile Agent Template (MAT) is a mobile agent system that is under study and development at the Institute of Computing Technology, Chinese Academy of Sciences and sponsored by the University of Wollongong, Australia. MAT is not an alternative to other mobile agent systems, but is an agent system that can provide the autonomy to mobile agents. MAT tries to support new Web applications, such as t...

Petri hypernets, a novel framework for modeling mobile agents based on nets-within-nets paradigm is presented. Hypernets employ a local and finitary character of interactions between agents, and provide means for a modular and hierarchical description. They are capable of modelling mobile agents tfrahat can dynamically change their hierarchy, and can communicate with each other and with the out...

Many areas such as electronic commerce, network management and information retrieval can benefit from the application of mobile agents technologies. The exploitation of mobile agents offers several advantages such as reduction of network latency, asynchronous execution, fault-tolerant behavior. However, a wider use of mobile agents is currently limited by the lack of a comprehensive security fr...

This article describes a decentralized secure migration process of mobile agents between Mobile-C agencies. Mobile-C is an IEEE Foundation for Intelligent Physical Agents (FIPA) standard compliant multi-agent platform for supporting C/C++ mobile and stationary agents. Mobile-C is specially designed for mechatronic and factory automation systems where malicious agents may cause physical damage t...

Mobile agents are a recent paradigm to facilitate the design and programming of distributed applications. However, whilst their popularity continues to grow, a uniform theory of mobile agent systems is not yet su ciently elaborated, in comparison with classical models of distributed computation. In this paper we show how to use mobile agents as an alternative model for implementing distributed ...

We formally define the mobile agent allocation problem from a system-wide viewpoint and then prove that it is strongly NPcomplete even if each agent communicates only with two agents. This is the first formal definition for scheduling mobile agents from the viewpoint of load balancing, which enables us to discuss its properties on a rigorous basis. The problem is recognized as preemptive schedu...

This paper models and formalizes a mobile logic programming multi-agent system (MLPMAS) for mobile environments. Such a system consists of a number of agents connected via wire or wireless communication channels. Agents communicate with each other via passing answer sets obtained by updating the information received from connected agents with their own private information. The interactions betw...

In this paper, we present an implementation of a Java-based framework for building mobile agents : MiLog (Mobile intelligent agents using Logic programming). MiLog provides logic programming and Java programming for developing intelligent agents since it helps users to effectively construct intelligent mechanisms. We address how to realize an anytime migration mechanism, a HTTP(Hyper Text Trans...

The paper presents the results of a performance analysis of mobile agents in a distributed network environment. Analytical models are developed and used to compare the performance of carrying out a simple management function with Mobile Agents (MA) or SNMP (Simple NetworkManagement Protocol). We examine how delay is affected by the size of the management domain and how each method behaves in bo...
