In order to overcome the problem of free-riding in current P2P system, we suggest applying social network theory. Based on our exploration of the overlapping research fields of social networks and peer-to-peer networks, we propose a new P2P framework within this paper. It specifies social...

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....

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,...

As information and communication technologies have spread throughout the world, countries have realized the importance of investing more and more in building ICT-relevant infrastructure. However, for fostering further information and communication technology (ICT) development, countries are in...

In this paper, we present an agent-based simulation system that allows modeling the interactions between software buyers and vendors in a software market. The market offers Software-as-a-Service (SaaS) and perpetual software (PS) licenses under different pricing schemes. Four dynamic pricing...

Service markets allow users to discover, purchase, and utilize services offered on a specific platform. As service platforms grow in number of users and variety of offerings, it raises the question of whether this phenomenon continues to benefit users. Based on a literature review, the paper...

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...

Are students from one of the high tech universities in the world fully aware of their permanent linkage to the global learning network, the World Wide Web? In their pockets, backpacks, and purses are the latest smartphones loaded will countless apps. But, how aware are these students of the use...

Shortcomings of transport network technologies were the main driver behind strong efforts of standardization organizations to develop control plane frameworks since 2001. Despite the findings of previous studies that the control plane framework deployment will lead to a 50 percent decrease in...

Service networks can be considered to be open innovation systems. It has led to research on the structure of these networks, concentrating on the static network topology and its effect on innovation. However, the research misses the changes of network positions over time. In this paper, we...
