| 摘 要： | 针对网格资源的特性，提出了一种基于熵的网格资源服务质量(QoS) 优化策略。其核心思想是提出了衡量网格资源服务QoS稳定性的新尺度——熵,并利用熵来选择QoS稳定性好的资源, 提高了资源的可靠性和准确性，从而在网格服务频繁变化的环境中尽可能地提供QoS保证。仿真试验表明该方法能有效地确保系统QoS，并获得近似最优的资源分配方案。

| Abstract: | According to distributed multimedia applications' characteristics,an entropybased quality of service(QoS) algorithm for grid resource is proposed for application's QoS.The key idea of the algorithm is to construct the new metric-entropy and select the best-stability QoS with the help of entropy metric to improve the reliability and accuracy of the resource management.So as to provide QoS guarantee in the grid service environment whose changes continuously.The simulation results show that this works are effectively and reach near results. |
