This paper describes an approach to make robotic systems “resource-aware”, in the sense that they can adapt optimally to the available computation and communication resources. A resource-aware application is one where the functionality implemented depends on the resources usage, such as timing information (latency, throughput) and power consumption. Allowing this flexibility introduces a recurs...

Network aware applications provide opportunities for adaptive resource allocations for both network resources and distributed hosting of critical applications. We propose an Automatic Dynamic Resource Management (AutoDRM) architecture for efficiently managing shared resources in tactical network environments without human operator intervention. The AutoDRM architecture was developed to resolve ...

Cloud computing offers on-demand access to large-scale computing resources in a pay-as-you go manner. Market-based resource allocation mechanisms are gaining popularity among commercial cloud providers to deal with dynamically fluctuating resource demands. For example, the recently introduced Amazon EC2 spot instances allow users to bid for computing resources and thus control the cost vs. reli...

In this paper, the grid computing system is seemed as an ecosystem. The object of the optimization resource management is to promote the balance and evolution of the computing ecosystem. The architecture of the ecosystem model based grid resource management system is presented, which has the self-aware and selfoptimization mechanism. The knowledge discovery based self-aware mechanism has the ab...

We present a powerful and flexible method for automatically checking the secrecy of values inside components. In our framework an attacker may monitor the external communication of a component, interact with it and monitor the components resource usage. We use an automata model of components in which each transition is tagged with resource usage information. We extend these automata to pass val...

Mobile users connected to wireless networks expect performance comparable to those on wired networks for interactive multimedia applications. Satisfying Quality of Service (QoS) requirements for such applications in wireless networks is a challenging problem due to limitations of low bandwidth, high error rate and frequent disconnections of wireless channels. In addition, wireless networks suff...

We present a status report on RAVE, our distributed, collaborative grid enabled visualization environment. We briefly review our architecture and related work, examine our collaborative support and relate this to an experiment carried out between SuperComputing 2004 (Pittsburgh, PA, USA) and the Cardiff School of Computer Science. Load distribution in RAVE is described and analysed, using a til...

This paper reports the development of the Concerto platform, which is dedicated to supporting the deployment of resource-aware parallel Java components on heterogeneous distributed platforms, such as pools of workstations in labs or offices. We propose a basic model of a parallel Java component and present some tools that facilitate the management and the deployment of such a component on a dis...
