Performance analysis of Network Coding (NC) is becoming an increasingly important issue in today's data communication systems. This is because of its success in achieving the min-cut capacity of multicast networks, leading to throughput improvement at the destination nodes. The implementation of NC requires a thorough investigation of its impact on relevant queuing systems. In this paper, we analyze...
Publish/Subscribe (P/S) systems and file sharing applications traditionally share the common goal of disseminating data among large populations of users. Despite this similarity, the former focuses on timely dissemination of small-sized notification messages, while the latter presumes larger types of bulk content with less emphasis on the time needed between release and delivery of data. In this paper,...
In this paper we consider a linear optimization approach for studying download finish times in peer-to-peer networks that allow but do not require coding. We demonstrate that using the network coding framework simplifies analysis even in scenarios where the optimal solution does not require coding. For example, we use the network coding framework to disprove the claim of Ezovski et al. that in the...
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...
