Web2.0 users can create new services by combining existing Web2.0 services that offer open programming interfaces. This system of service composition forms a network, which we call the Web2.0 service network. A node of the Web2.0 service network represents a service. A link between two nodes...

In the Grid Computing environment, many users need the results of their calculations within a specific period of time. Those users are willing to pay for getting their work completed on time. However, this requirement must be agreed on in a Service Level Agreement (SLA) by both, the user and the...

This paper investigates the impact of determination of an original initiator of transmission on demand as well as profits of the providers. For that purpose we present a new model, called differentiated traffic-based interconnection agreement (DTIA) that differentiates traffic into two types,...

Cost allocation between interconnected networks is based on measured traffic flows. This principle, however, does not provide a fair way for sharing costs. In this paper, a new bilateral model, called Differentiated Traffic-based Interconnection Agreement (DTIA) for intercarrier compensation is...

In terms of intercarrier compensation traffic flows are measured to allocate the costs between networks. This method provides a poor basis for sharing any costs. In this work we analyze the benefits of the traffic differentiation on the interconnection charges in unilateral and bilateral...

This paper addresses the inter-provider costs sharing issue by exploring the effect of the traffic differentiation on the interconnection payments. In particular, we determine an original initiator of a transmission by means of traffic differentiation into two types, referred to as native and...

Within this paper, we present the GridEcon Platform, a testbed for designing and evaluating economics-aware services in a commercial Cloud computing setting. The Platform is based on the idea that the exact working of such services is difficult to predict in the context of a market and,...

One of the important characteristics of Web2.0 is the collaboration between Web2.0 service providers. They allow users (i.e., providers, developers, consumers) to combine their services. The prerequisite for this collaboration is openness of the Web2.0 service system. Although the Web2.0...

This paper applies the theory of social networks to P2P systems, creating a social-network-based P2P network topology formation algorithm for file sharing. The algorithm extends the Gnutella P2P file sharing technology, which uses super nodes for searching and for relaying shared files between...

Volunteer Grids, in which users share computing resources altruistically, play a critical role in fostering research. Sharing and collaboration in Volunteer Grids is determined by many factors. These determinants define the participation in Grids and the amount of contribution to such Grids....
