Analyzing the Dynamics and Resource Usage of P2P File Sharing by a Spatio-temporal Model

چکیده
In this paper we study the population dynamics and resource usage optimization of a P2P file sharing system, where the availability of the requested file is not guaranteed. We study the system first by a deterministic fluid model and then by a more detailed Markov chain analysis that allows estimating the life time of the system. In addition, the underlying topology of the network is modelled by a simple geometry. Using the resulting spatio-temporal model we assess how much the resource usage of the network can be reduced, e.g., by selecting the nearest seed for download instead of a random one.

P2P Network Trust Management Survey
Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...
متن کاملA Resource Exchange Architecture for Peer-to-Peer File Sharing Applications
A peer-to-peer (P2P) file sharing network provides a resource sharing platform for Internet users. To increase higher-degree resource sharing, heterogeneous P2P file sharing networks need a way to collaborate and communicate with each other. Based on the approach of interconnecting heterogeneous P2P file sharing networks, users on one P2P file sharing network can share resources and search data...
متن کاملTrust in the Social Computing: The Case of Peer-to-Peer (P2P) File Sharing Networks
Social computing and online communities are changing the fundamental way people communicate and share information. Social computing focuses on how users may have more autonomy to express their ideas and participate in social exchanges in various ways, one of which may be Peer-to-Peer (P2P) file sharing. Given the risk of opportunistic behavior by malicious and/or criminal communities within the...

Background: Congenital Hypothyroidism (CH) is one of the reasons for mental retardation and defective growth in neonates. It can be treated if it is diagnosed early. The congenital hypothyroidism can be diagnosed using newborn screening in the first days after birth. Disease mapping helps to identify high-risk areas of the disease. This study aimed to evaluate the pattern of CH using the Poisso...
متن کاملUnderstanding Pollution Dynamics in P2P File Sharing
Pollution in P2P file sharing occurs when a large number of decoy files are injected into the P2P system. Since peers “serve” each other in the P2P file sharing system, it is obvious that pollution dynamics are closely related to user behavior. Therefore, we first conduct a human subject study to investigate user behavior. We identify the factors that are key to model user behavior, e.g., coope...
