    Implementing an application as a mobile agent may improve the application's functionality and performance, but may have a detrimental effect on overall system performance. We consider the effect of moving an application from a client to a file server (as an agent), both on the application and the server. Under what circumstances does application performance improve, and does it come at the expense... View full abstract»

    Many real-world tasks can be decomposed into pipelines of sequential operations (where subtasks may themselves be composed of one or more pipelines). JGram is a framework enabling rapid development of such multi-agent systems. Each agent's services are specified in the JGram Description Language (JDL), and automatically converted into Java source templates. These services may be invoked synchronou... View full abstract»

    Mobile agents, programs that move within a system performing a set of tasks, are an active field of research. The focus of current research, however, is on the development of execution platforms and applications for mobile agents and not on methodologies for building agents. Creating mobile agents can be tedious and susceptible to errors. We propose a framework where the agent is composed using a ... View full abstract»

    We study the distributed infrastructures required for location-independent communication between migrating agents. These infrastructures are problematic: different applications may have very different patterns of migration and communication, and require different performance and robustness properties; algorithms must be designed with these in mind. To study this problem we introduce an agent progr... View full abstract»

    At present, the de-facto platform for providing contents in the Internet is the World Wide Web. A technology, which is now emerging on the Web, is content based retrieval (CBR). A content based query matches examples or prototypes to known instances of a certain media type based on a measure of similarity. For efficiency, similarity measures are frequently computed on sets of discriminant features... View full abstract»

    In order to maintain their performance in a dynamic environment, agents may be required to modify their learning behavior during run-time. If an agent utilizes a rule based system for learning, new rules may be easily communicated to the agent in order to modify the way in which it learns. However if an agent utilizes a connectionist based system for learning, the way in which the agent learns typ... View full abstract»

    Role theory deals with collaboration and coordination; roles have also been applied to distributed systems management and to agent and robot systems. However, it has been difficult to realize these representations in an automated or semi-automated system, due to the lack of an adequate formalism and corresponding abstractions in software. Role models are relatively new concepts in object-oriented ... View full abstract»

    An often-claimed benefit of mobile agent technology is the reduction in communication costs. In particular, the area of information filtering has been proposed for the application of mobile filter agents. However, the effective coordination of agents, which takes into account the current network conditions, is difficult to achieve. This paper analyses the situation where data distributed among var...

    In the past few years there has been an enthusiastic interest in mobile agent technology and several platforms have been developed. There are some comparisons in the literature about the functionality of some mobile agent systems. However, none of those studies includes a direct comparison between the performance of the platforms. We present the results of an experimental study where we compare th... View full abstract»

    The paper proposes a Java-based mobile agent infrastructure, TRAVELER, to support wide area parallel applications. Unlike other meta-computing systems, TRAVELER allows users to dispatch their compute-intensive jobs as mobile agents via a resource broker. The broker forms a parallel virtual machine atop servers to execute the agents. Since the agents can be programmed to satisfy their goals, even i... View full abstract»

    The provision of a reliable communication infrastructure for mobile agents is still an open research issue. The challenge to reliability we address in this work does not come from the possibility of faults, but rather from the mere presence of mobility, which slightly complicates the problem of ensuring the delivery of information, even in a fault-free network. For instance, the asynchronous natur... View full abstract»

    Although mobile agents are a promising technology, the large-scale deployment of agents and the existence of hosts running agencies will not happen until proper security mechanisms are well understood and implemented. When considering global open environments such as the Internet, mobile agents can be the victims of attacks by malicious hosts. We present a security framework that protects agents f...
