摘要: 为进一步提高资源协同的效率,从资源的静态功能特性出发,定义了相似度函数,给出了基于功能的资源协同算法;从资源的实时状态信息出发,给出了基于运行时QoS特性的资源协同算法.建立了综合考虑资源的功能特性和运行时QoS特性的资源协同机制,通过基于功能的资源协同工作,提供满足用户静态功能要求的资源候选集;通过基于运行时QoS特性的资源协同工作,从满足用户静态功能要求的资源候选集中实时动态地选择满足用户QoS要求的优质资源.实验结果表明,提供的基于语义描述的资源协同机制提高了资源协同的成功率、服务质量和运行效率.

Abstract: In order to improve the efficiency of the resource cooperation, according to the static functional characteristics, the similarity function and function-based resource cooperation algorithm was provided; according to the runtime QoS characteristics, the runtime QoS resource cooperation algorithm was given. On the basement of above work, a resource cooperation which combines the effects of static functional resource cooperation and runtime QoS nonfunctional resource cooperation was put forward. The top-rank candidate resources which were able to satisfy the end user-s task were provided through the function-based resource cooperation, and the high quality resource could be gotten from the given top-rank candidate resources through the runtime QoS resource cooperation. The evaluation on the cooperation mechanism shows that the semantic-based service resource cooperation mechanism promotes the success rate, service quality and executes efficiency for resource cooperation.
