| 中文摘要 | 为了解决智能空间中多媒体应用的服务合成问题,实现服务选择的优化,改善服务合成的性能,提出一种高效率的动态扩展优化的服务合成策略。该策略以媒体显示服务选择为优化目标,以用户需求和移动特性为约束条件,采用源端到目标端的路由路径扩展的查找方法建立基于部分数据特征匹配的合成路径,并通过效果预测来自适应地调整服务,以动态地优化网络资源的使用。实验结果表明:该策略的合成开销平均约为传统固定服务图方法合成开销的1/4。可见该策略优化合成服务的配置,显著减少了服务合成的消息负载,更好地适应动态环境的变化。; An efficient service composition strategy for dynamic extension optimization of multimedia composition applications was developed to optimize composite services and improve the performance of service composition in smart space.The strategy uses the selection of the media presentation services as the optimization target with user and mobility requirements as constraints.The composition path using the routing path extension search method partially matches the data characteristics from the source to the destination node.A forecasting method is then used to regulate the service to dynamically optimize the usage of network resources.Tests show that the composition message overhead with this strategy is approximately one-fourth that of the traditional fixed service graph.Thus,the strategy achieves an optimized configuration of composite services with a notable reduction of composition message overhead which adapts to the dynamic environments. |
