For single-layer content distribution, the piece-picking algorithm only needs to ensure that content pieces are downloaded in time for display. When layered content is distributed over a peer-to-peer network, the piece-picking algorithm needs to be modified to ensure that the best possible quality is displayed while all desired pieces still have to be received before their deadline expires. In this paper, the piece-picking problem for layered content is analyzed and a number of piece-picking algorithms for layered content based on the solutions for the knapsack problem are presented. Furthermore, an evaluation of these algorithms is performed and possible applications are discussed.}, doi = {10.1145/1877891.1877908}, isbn13 = {978-1-4503-0169-5}, keywords = {knapsack problem, layered/scalable content, piece utility calculation, piece-picking}, language = {EN}, location = {Firenze, Italy}, pdf = {}, talkdate = {2010.10.29}, talktype = {poster}, url = {} }
