In this study, we develop a theoretical model based on social network theories and analytical methods for exploring collaboration (co-authorship) networks of scholars. We use measures from social network analysis (SNA) (i.e., normalized degree centrality, normalized closeness centrality,...

In this paper, we introduce an analytical model for maximizing social welfare, which can be used for finding the optimal offering of a set of software services. The analytical model also explains the impact of service flexibility on customer¡¯s selection of business services and on the revenue...

This study examines the customer satisfaction of telecomm-unication service in the Kurdistan region of Iraq. The purpose is to identify the key factors determining the customer satisfaction of telecommunication service. A conceptual model is specified and a number of hypotheses tested with a...

The increasing demand for bandwidth and the error-prone, costly, and long-lasting service provisioning process force carriers to find new ways of automatic service provisioning. Despite the introduction of numerous path computation procedures, suitable for WDM-technology-based networks, very few...

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,...

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...

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...
