XML-centric models of computation have been proposed as an answer to the demand for interoperability, heterogeneity and openness in coordination models. Recently, Bigraphical reactive systems has been introduced as a theoretical meta-model for reactive systems with semi-structured state. We present an XML representation of bigraphical reactive systems(More)
XML-centric models of computation have been proposed as an answer to the demand for interoper-ability, heterogeneity and openness in coordination models. We present a prototype implementation of an open XML-centric coordination middleware called Distributed Reactive XML. The middle-ware has as theoretical foundation a general distributed extensible process(More)
In this report a routing algorithm Ant Routing System (ARS) is presented. ARS is based on a general-purpose metaheuristic named Ant Colony Optimization, which is a framework for building ant-inspired algorithms. ARS is applied as the routing algorithm in a simulated package-switched point-to-point network. It is investigated whether ARS is able to obtain an(More)
Theory-Bigraphical Reactive Systems Reactive XML is based on Robin Milner's Bigraphical Reactive Systems [1] and developed as part of the Bigraphical Programming Languages project at ITU[6]. Bigraphical Reactive Systems can be seen as a general meta-model for reactive systems that combines nested location structures as in Cardelli's Ambient calculus and(More)
Introduction We have decided to give a low priority to the description of our implementation in this report (even though we have about 8000 lines of Java code approximately half of these is comments and JavaDoc), and only give a general view through UML and descriptions of the respective designs where appropriate. This small section is just to draw(More)
