Mobile agents can be seen as a new paradigm for distributed computing. At Friedrich Schiller University, we have developed our own mobile agent system, called Tracy. Tracy is implemented in Java 2. One characteristic of mobile agents is their autonomy and pro-activity. We designed a framework on top of Tracy to support our research in this domain. Our framework consists of three modules. The Map Module collects information on the available network of agent servers (agencies). By this means, a mobile agent is able to locate services within the network. Furthermore, the framework provides a route planning module and an optimization module, which minimizes network load respectively transmission time. These modules support a fast and efficient navigation through the network, which is an environment with an inherently dynamical behavior. The basis for this project is the Tracy Domain Service, which is a hierarchical arrangement of agent servers that groups agencies into a federation of networked local clusters, so called domains.The focus of the paper is to evaluate the basic concepts and the actual modules of this framework. We made some measurements to characterize the modules' quality and to identify problems. Furthermore, we take a first look at the possible performance enhancement of mobile agents which are using the framework.

Mobile agents can be seen as a new paradigm for distributed computing. One characteristic of mobile agents is their autonomy and pro-activity. This article present a framework designed on top of PMADE (Platform for Mobile Agent Distribution and Execution) to support our research in this domain. Our framework consists of three modules. The Map Module collects information on the available network of agent hosts (AHs) and a mobile agent is able to locate services within the network with the help of this module. Furthermore, the framework provides a Route estimating module and an optimization module, which minimizes network load. These modules support a fast and efficient navigation through the network, which is an environment with an inherently dynamical behavior. The basis for this work is the PMADE Domain Service, which is a hierarchical arrangement of AHs that groups AHs into a federation of networked local clusters, so called domains. This paper also evaluates the basic concepts and the actual modules of the developed framework and made some measurements to characterize the modules quality and to identify problems

Abstract.With the growing size of distributed systems and the higher number of available resources and services in networks dynamical aspects become more and more important in systems engineering. We believe that there is a real need for decentral, self-organizing structures to cope with the upcoming challenges. In this paper we describe a framework which provides a self-organizing infrastructure that allows to link otherwise autonomous elements in a flexible way and adapts dynamically to changes in the underlying network. This framework is implemented as an extension of the mobile agent system Tracy, which is also a product of our university. The Tracy Domain Management module is part of the framework and provides the basis for segmenting the infrastructure. Another module we are going to discuss in this paper facilitates autonomous and proactive routing of mobile agents. Agents form the application layer of the system. Routing is triggered by the needs an agent inherits from its owner and then matched to the resources and services available in the network in an iterative fashion. We describe concepts, design issues and first results of our work with Tracy and the use of these additional Tracy modules.
