摘要
针对P2P流媒体中现有算法在数据调度时不够公平的问题,提出了一种新的具有激励作用的算法模型。该算法模型可以根据节点的丢包率、贡献效率动态调节节点带宽分配以达到接收节点利益理性最大化和系统整体公平,提高了系统传输效率。仿真实验表明,该算法模型促进了节点的参与传输调度,达到了维持系统公平的目的。
In order to solve the unfairness in the existing algorithm on data scheduling in P2P media streaming, a new algorithm model having incentive function was proposed. It can dynamically adjust bandwidth allocation of peers according to their packet loss and contribution rate to realize maximum of receiving peer＇s interests rationally and fairness of the whole system, and enhance system transmission efficiency. The simulation results show that this algorithm model motivates peers to participate in data scheduling and maintains system fairness.
