New P2P Sharing Incentive Mechanism Based on Social Network and Game Theory

[[abstract]]P2P technology has been used widely in file and live media streaming sharing fields. But the architecture of P2P technology which we used is imperfect. In P2P system, most users are free-rider. They were not sharing their own resource because the architecture has no perfect incentive mechanism. Therefore, in this research, we propose a novel incentive mechanism (NIM) that considers useful information in social network and various important factors of the peers in P2P architecture to affect the system performance. In addition, we analyze the effectiveness of NIM by game theory. The simulation results show that deploying NIM to P2P system not only promotes the peers to spontaneous sharing their own resource but also decrease amount of free-rider.[[conferencetype]]國際[[conferencedate]]20120326~20120329[[iscallforpapers]]Y[[conferencelocation]]Fukuoka, Japa

Business model with discount incentive in a P2P-cloud multimedia streaming system

Today P2P faces two important challenges: design of mechanisms to encourage users' collaboration in multimedia live streaming services; design of reliable algorithms with QoS provision, to encourage the multimedia providers employ the P2P topology in commercial live streaming systems. We believe that these two challenges are tightly-related and there is much to be done with respect. This paper analyzes the effect of user behavior in a multi-tree P2P overlay and describes a business model based on monetary discount as incentive in a P2P-Cloud multimedia streaming system. We believe a discount model can boost up users' cooperation and loyalty and enhance the overall system integrity and performance. Moreover the model bounds the constraints for a provider's revenue and cost if the P2P system is leveraged on a cloud infrastructure. Our case study shows that a streaming system provider can establish or adapt his business model by applying the described bounds to achieve a good discount-revenue trade-off and promote the system to the users

Current Trends, Characteristics, Challenges and Future of P2P

. Abstract-Peer to peer (P2P) network is an approach of connecting computers in such a way that all connected computers share equivalent responsibility for processing data. The aim of this study to discuss the current Trends of P2P networks, which includes broad catching, new knowledge development in P2P and wireless devices in P2P. Later in this study P2P characteristics along with its challenges will be explored. Later this study will highlight on future trends of P2P such as, videos, audio casting and P2P mobile applications. Finally this study will conclude with future work in this field. Index Terms-P2P, trends in P2P, P2P challenges, future of P2P
