Delay-sensitive delivery of scalable coded images over peer-to-peer networks

We propose an algorithm to optimize the delivery quality of fine-scalable coded images on peer-to-peer networks when a requesting peer is delay-sensitive and has to display the images within a certain delay bound. First, we introduce the peer assignment problem using an example. Then, we formally define and formulate this problem as two integer programming problems, from which we derive an optimal peer assignment solution. Finally, we carry out experiments to verify the excellent performance of the proposed peer assignment algorithm by comparing it with two heuristic schemes.
