Abstract

Multiple distribution trees and multiple description (MD) coding are highly robust since they provide redundancy both in network paths and data. However, MD coded streaming includes a redundant information, which results in additional bandwidth consumptions in entire distribution trees. In this paper, we deploy core nodes in distribution tree, and give a role of MD coding to each core node, instead of a source node then we show how amount of bandwidth consumption can be reduced. Since the problem of finding an optimal set of core nodes is proved to be NP-hard, an intuitional heuristic-based algorithm is proposed. The simulation results show that our heuristic algorithm reduces the bandwidth consumptions by about 25% in the hierarchical topology compared to the MD coding in source node only.
