In the past few years, Mobile agent technology is one of the emerging, fastest growing and promising concepts for the development of applications. A mobile agent is composition of computer program that proceed autonomously for a user or application moving in the heterogeneous communication environment. This survey presents “pure fault tolerance technique “that enables a system to continue opera...

The reliable execution of a mobile agent is a very important design issue in building a mobile agent system and many fault-tolerant schemes have been proposed so far. To further develop mobile agent technology, reliability mechanisms such as fault tolerance and transaction support are required. For this purpose, we first identify two basic requirements for fault-tolerant mobile agent execution:...

In this paper, we introduce a reliable directory service and message delivery mechanism for large-scale mobile agent systems to address both agent mobility and directory service node failures. The mechanism enables each mobile agent to keep its forwarding pointer only on the small number of its visiting nodes in an autonomous manner. As this desirable feature has every mobile agent’s migration ...

Mobile agent technologies are getting popular as means for an efficient way to access network resources. Because an application using mobile agents has some unique problems caused by frequent creation, migration and disappearance of mobile agents, a mobile agent platform has to provide not only agents and their execution engines but some functions and mechanisms which are specialized to mobile ...

Two methods to implement privacy in network communication, anonymity and DCSC (data confidentiality and secure computation) are analysed and compared in regard to privacy in mobile agent applications. It is illustrated that privacy through DCSC is more suitable in mobile agent applications. To support this conclusion, privacy is concretely implemented in a bidding mobile agent scheme in this pa...

Agent technology is emerging as an important concept for the development of distributed complex systems. A number of mobile agent systems have been developed in the last decade. However, most of them were developed to support only Java mobile agents. In order to provide distributed applications with code mobility, this article presents a library, the Mobile-C library, that allows a mobile agent...

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...

Mobile agent technology is a new paradigm of distributed computing that can replace the conventional client-server model. However, it has not become popular due to some problems such as security. Threats to mobile agent security generally fall into three main classes: disclosure of information, denial of service, and corruption of information. Four threat categories are identified: threats stem...

Agent mobility presents challenges to the design of efficient message transport protocols for mobile agent communications. A practical mobile agent communication protocol should provide location transparency to the programmer and thus need to keep track of the movement of an agent. In addition, because of the asynchronous nature of message passing and agent migration, how to guarantee the deliv...

A collection of executable programs known as a Mobile agent (MA) migrates from one execution platform to another in a heterogeneous network to perform various tasks on the behalf of its user [1]. The employment of mobile agents introduce many benefits to the distributed computing including network load reduction, overcoming network latency, executing dynamically, asynchronously and autonomously...
