Application layer networks are software architectures that allow the provisioning of services requiring a huge amount of resources by connecting large numbers of individual computers, like in Grid or Peer-to-Peer computing. Controlling the resource allocation in those networks is nearly impossible using a centralized arbitrator. The network simulation project CATNET will evaluate a decentralized mechanism...
The vision of an open and global Internet of services (IoS) is driven by globalization and fast changing settings when trading on a world-wide scope. It requires automated on-line techniques for handling services and resources themselves, for advertising and discovery as well as for the on-the-fly negotiation of proper terms for their use. In such a setting covering completely different branches and...
Electronic commerce mechanisms are mainly investigated in two independent research areas: service-oriented computing (SOC) and multi-agent systems. The former as a means to deliver electronic services of various granularity and the latter as a testbed of electronic negotiation mechanisms. However, both research areas heavily rely on each other. On the one hand, service-oriented architectures need...
Economic resource allocation in application layer networks (such as grids) is critical to allow applications and users to effectively exploit computational and data infrastructures like service-oriented computing as a utility. Thus, the evaluation of resource allocation strategies plays a major part in the selection of a resource allocation method. This paper presents an evaluation framework for resource...
Multi-agent software systems can be modelled as complex dynamic systems in which agent adaptation and interaction occur continuously and concurrently. A genetics-inspired view has interaction occurring via exchange of agent characteristics encoded as genes, plus measures of success. An economics-inspired view has agent adaptation driven by changes in prices, and supply and demand. This paper describes...
