摘要
在普适环境下,由于设备、网络环境等的动态性,一些服务的提供者容易脱离当前的计算环境,从而造成服务组合方案失效。针对普适环境的特点,以及可靠服务组合的要求,提出了一种普适环境下基于图的可靠服务组合机制RScMPG,该机制从"预防"和"检测-补偿"的角度出发,在"生成可靠服务组合方案"和"监护服务组合正确执行"两个层面上,提高了服务组合的可靠性。
In pervasive environments,devices and network environments are extremely heterogeneous and highly dynamic.So,service providers are more possible to disconnect the current computing environments,leading to the failure of service composition.After considering pervasive computing features,and the requirements of reliable service composition,this paper gave a reliable service composition mechanism——RScMPG.RScMPG ensures service composition's reliability by "Generating More Reliable Service Composition Plan" and "Monitoring the Implementation of Service Composition".
