  • Addressing the Non-Cooperation Problem in Competitive P2P Systems
    2003
    Co-Authors: Sepandar D. Kamvar, Beverly Yang, Hector Garcia-molina
    Abstract:

    Large-scale competitive P2P systems are threatened by the non-cooperation problem, where peers do not forward queries to potential competitors. While non-cooperation is not a problem in current P2P free File-sharing systems, it is likely to be a problem in such P2P systems as pay-per-Transaction File-sharing systems, P2P auctions, and P2P service discovery systems, where peers are in competition with each other to provide services. Here, we motivate why non-cooperation is likely to be a problem in these types of networks and present an economic protocol to address this problem. This protocol, called the RTR protocol, is based on the buying and selling of the right-to-respond (RTR) to each query in the system.

  • ICDCS - Non-Cooperation in Competitive P2P Networks
    25th IEEE International Conference on Distributed Computing Systems (ICDCS'05), 1
    Co-Authors: Beverly Yang, Sepandar D. Kamvar, Tyson Condie, Hector Garcia-molina
    Abstract:

    Large-scale competitive P2P networks are threatened by the non-cooperation problem, where peers do not forward queries to potential competitors. Non-cooperation will be a growing problem in such applications as pay-per-Transaction File-sharing, P2P auctions, and P2P service discovery networks, where peers are in competition with each other to provide services. Here, the authors showed how non-cooperation causes unacceptable degradation in quality of results, and present an economic protocol to address this problem. This protocol, called the RTR protocol, is based on the buying and selling of the right-to-respond (RTR) to each query in the network. Through simulations it is shown how the RTR protocol not only overcomes non-cooperation by providing proper incentives to peers, but also results in a network that is even more effective and efficient through intelligent, incentive-compatible routing of messages

  • Encyclopedia of Information Systems - Transaction Processing Systems
    Encyclopedia of Information Systems, 2003
    Co-Authors: Sasan Rahmatian
    Abstract:

    ACID properties A Transaction is characterized by four properties referred to as the ACID properties: atomicity, consistency, isolation, and durability. database update The real effect of a Transaction; it takes one of three forms: add, change, and delete. logical conception A view of a TPS that focuses on what information flows int%ut of it, and what processes are performed on that information. It is relatively stable and permanent. master File A File that contains data about permanent entities, such as customers, products, suppliers, and employees. Its contents are updated by a Transaction File. physical conception A view of a TPS that focuses ... on the technology used in entering the data, producing the information, and performing the processes. It is dynamic and transient due to frequent technological advances. ripple effect Occurs when Transaction data travel to all the other parts of the organization where they are needed. scalability The ability of an application or platform to be expanded in terms of capacity to accommodate a larger number of users or Transactions than originally planned without requiring significant changes in procedure. Transaction A business event whose relevant attributes need to be recorded internally (in the corporate database) as well as externally (for the benefit of external stakeholders, such as customers, suppliers, business partners, and regulators) due to

  • Association Rule Mining among web pages for Discovering Usage Patterns in Web Log Data
    International Journal of Advanced Research in Computer Science, 2013
    Co-Authors: L. Mohan, T.venu Gopal
    Abstract:

    The objective of this project is to find the associations among different web pages in a web log File of a website, and then divide the page of each user accessed, who is likely to visit the Web site more than once and create individual sessions. This can be done by computing the association rules in relation to the web pages by using the information from the web log File maintained by its web server. Such information containing association rules gives a broad view of user sequences. It can be extended to any field of activity that involves large bulks of data. This paper is concerned with web usage mining of web mining. The server maintains the information of usage data sequences done by different users. The web log File has the information about the different pages that have been accessed by the users and the secondary information about each URL. Considering that information, in order to perform an association rule analysis, which is also known as market basket analysis, there’s the need to define the basket; in the web environment this is not as clear as in a real supermarket. A phase of Transaction identifiers is needed. Finally, after the application of one of these methods, the Transaction File is created, the basket entities are defined and the discovery process of association rules can go on with the application of an Association Rule algorithm such as the Apriori one. To find the confidence among the web pages accessed, the user gives a user specified threshold value such as minimum support and minimum confidence values, which determines the probability of accessing a web page when a set of web pages are accessed.
