Incentive Mechanism Design for Heterogeneous Peer-to-Peer Networks: A Stackelberg Game Approach

Abstract: With high scalability, high video streaming quality, and low bandwidth requirement, peer-to-peer (P2P) systems have become a popular way to exchange files and deliver multimedia content over the internet. However, current P2P systems are suffering from "free-riding" due to the peers' selfish nature. In this paper, we propose a credit-based incentive mechanism to encourage peers to cooperate with each other in a heterogeneous network consisting of wired and wireless peers. The proposed mechanism can provide differentiated service to peers with different credits through biased resource allocation. A Stackelberg game is formulated to obtain the optimal pricing and purchasing strategies, which can jointly maximize the revenue of the uploader and the utilities of the downloaders. In particular, peers' heterogeneity and selfish nature are taken into consideration when designing the utility functions for the Stackelberg game. It is shown that the proposed resource allocation scheme is effective in providing service differentiation for peers and stimulating them to make contribution to the P2P streaming system.

An agile service interaction manager for intelligent network services

Abstract: A method and system for responding to a trigger condition detected during the handling of a call connection in an intelligent network (IN). Upon receipt of an IN trigger, a service interaction manager (40) in a service control point (14) queries (37) a home location register (60) for a subscriber involved in the call connection requesting subscriber subscription information. The service interaction manager also queries (95) a service library (50) associated with the service control point to determine which of an implicated set of services are currently available in the service library and what the properties of those services are. Depending upon which services are available, which services are in the subscriber's subscription list, and the service priority information received from the home location register and the service library, including the properties data from the service library, the service interaction manager reduces the list of implicated services to an applicable set of services and generates a customized execution sequence for the applicable services. Thereafter, at least one of the applicable services is executed (108) in accordance with the customized execution sequence.

Analysis of resource sharing in information providing services

Abstract: The key to an economical service is in the sharing of physical resources among the customers. This applies to the information storage and sourcing devices, as well as to the transmission bandwidth. One of the possible solutions to the resource sharing problem is the grouping of customers with similar service requests, and broadcasting the information rather than granting the service individually. The customers' behavior (in particular, the customers' patience) is modeled, and the service performance for different service scenarios is analyzed. It is shown that in case of the threshold-activated service scenario, it is possible to optimize the service performance by using the statistics of the service requests and customer patience. >

Web Single Sign-On Authentication using SAML

Abstract: Companies have increasingly turned to application service providers (ASPs) or Software as a Service (SaaS) vendors to offer specialized web-based services that will cut costs and provide specific and focused applications to users. The complexity of designing, installing, configuring, deploying, and supporting the system with internal resources can be eliminated with this type of methodology, providing great benefit to organizations. However, these models can present an authentication problem for corporations with a large number of external service providers. This paper describes the implementation of Security Assertion Markup Language (SAML) and its capabilities to provide secure single sign-on (SSO) solutions for externally hosted applications.
