Abstract:

In the Peer-to-Peer(P2P) Video-on-Demand(VoD) system, in order to make full use of nodes' upload bandwidth resources, from the view point of date request amount, a fuzzy control realization of data scheduling strategy is proposed. According to the strategy, a node takes its buffer and its upstream bandwidth as fuzzy variables, generates fuzzy decision based on the fuzzy rule, and dynamically calculates the amount of data request to neighbor nodes and the server by fuzzy decision. Simulation result shows that the strategy improves the overall performance of the P2P media streaming system.

Key words: data scheduling, the amount of data request, fuzzy control, streaming, VoD, peer-to-peer(P2P) network
