资源有限的微云服务模型研究
Study of Resource Limited Service Model of Cloudlets
摘要
Abstract
Cloudlets are small self-maintained clouds.They improve the overall performance of mobile services through balancing user access requests.In practice,the dispersed user demand changes with time,and the service resources of cloudlets need to be deployed in advance according to the prediction of the required resources.Therefore,in order to optimize the overall performance of the system resource utilization,queuing theory is used to construct resource limited service model of cloudlets which fits in with the birth and death processes.Then,the comparison between single and multiple queues show that the single queue model with multiple virtual cores is better than the multi-queue model with single virtual core under the same service intensity.Experimental result showes that the service model of cloudlets can further optimize the overall system performance with the increase of the virtual cores.关键词
