P2P networks suffer from the free-riding problem, wherein users connect to the network only to use the resources, but do not donate any resources themselves. A popular approach to overcome this problem is to reward peers who share their resources, through payments. This has given a fresh lease of life to micropayments schemes, which are now being used in such networks. P2P Micropayment schemes ...

This work describes the prototype of the DFG Collaborative Research Center 1053 on ’Multi Mechanism Adaptation for the Future Internet’ (MAKI) on switching between network mechanisms during runtime. The replacement of whole network mechanisms of a system is called a transition. Transitions are necessary when environmental conditions change significantly. In this demonstration we show the advant...

The concept of the “future Internet” has evolved amongst researchers recently to relieve the tremendous pressure on the current Internet infrastructure to support the heterogeneous networking technologies, mobile devices, increased population of users, and also the high user requirements for real-time services and applications. Peer-to-Peer (P2P) Video on Demand (VoD) streaming technologies are...

With processor and memory technologies pushing the performance limit, the bottleneck is clearly shifting towards the system interconnect. Any solution that addresses PCI’s bus-based interconnect, which has serious scalability problems, must also protect the huge legacy infrastructure. PCI Express provides such an evolutionary approach and allows a smooth migration towards building a highly scal...

In a Peer-To-Peer (P2P) system, autonomous computers pool their resources (e.g., les, storage, compute cycles) in order to inexpensively handle tasks that would normally require large costly servers. The scale of these systems, their \open nature," and the lack of centralized control pose diÆcult performance and security challenges. Much research has recently focused on tackling some of these c...

content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....

There is much interest in crowdsourcing information that is distributed among many individuals, such as the likelihood of future events, election outcomes, the quality of products, or the consequence of a decision. To obtain accurate outcomes, various game-theoretic incentive schemes have been proposed. However, only prediction markets have been tried in practice. In this paper, we describe an ...
