摘要:

随着物联网与SOA的发展,物联网环境下以服务为资源的竞争问题越来越凸显。为了解决该问题,从资源优化的角度对该问题进行了研究与建模分析。利用资源调度机制和服务选择机制建立了服务调度模型;然后运用排队论对本模型进行了时延特性分析。模拟实验结果表明,本文的方法能够在有限的服务资源情况下保持服务请求的公平性,缓解高优先级服务请求的时延及时延抖动性,同时能在一定程度上满足用户的个性化需求。

Abstract:

With the repaid development of the Internet of Things (IoT) and ServiceOriented Architecture (SOA), the problem of service resource competition becomes increasingly severe. In order to solve the problem, this paper studies on it from the perspective of resource optimization. Firstly, a service scheduling model is established based on the theory of resource scheduling and service selection mechanism. Secondly, the delay performance of the scheduling model is analyzed by using the queue theory. The simulation experiments demonstrate that the proposed method is efficient. It can not only guarantee the fair attainability of requesters, but also relieve the delay and delay jitter performance. Meanwhile, to some extent, it can meet the individual requirements in the case of limited service resources.
