This paper presents an approach to a user authentication system for web applications using JME enabled cellular phone as an authentication token. Most of the existing web based user authentication systems use user IDs and passwords to authenticate users. However, since its inception, the internet has been the witness to increasing number of attacks resulting sensitive information like user IDs, passwords...
Peer-to-peer (P2P) systems provide a scalable way to stream content to multiple receivers over the Internet and has become a major type of application traffic. The maximum rate achievable by all receivers is the capacity of a P2P streaming session. We provide a taxonomy of the problem formulations. In each formulation, computing P2P streaming capacity requires the computation of an optimal set of...
Peer-to-peer live streaming is a promising way for service providers to offer high-quality IPTV to consumers at reasonable cost. The fundamental problem in peer-to-peer streaming is its capacity problem, or the maximum supported stream rate for a given network with a given peer selection constraint. This problem has been widely studied for small networks where the number of downloading peers is unlimited...
In this paper, we study the problem of utility maximization in peer-to-peer (P2P) systems, in which aggregate utilities are maximized by running distributed algorithms on P2P nodes that are constrained by their uplink capacities. This may be understood as extending the seminal flow control framework in (F. P. Kelly et al., 1998) and (S. H. Low et al.,1999) from single-path unicast over general topology...
