摘　　要：随着物联网与SOA(Service-Oriented Architecture,SOA)的发展,物联网环境下服务资源的竞争问题越来越凸显.目前,轻量级的服务模型、通信协议以及匹配方法等方面的研究难以实现对服务资源的优化利用及用户对服务的个性化需求.对此,本文从资源调度的角度进行了研究与建模分析.利用资源调度机制和回馈机制建立了服务调度模型,提出了基于回馈的服务等待队列,提高服务选择准确率.运用排队论相关知识对本模型进行了时延特性分析.实验结果表明,本文的方法能够服务资源有限的情况下降低服务请求的时延,保证服务请求的相对公平,同时很好的满足用户的个性化需求.With the development of The Internet of things （IoT） and service-oriented architecture,the service computing resources are progressively competed in IoT. Currently,the problem is commonly coped with the method of proposing lightweight communicating pro- tocol, service component and service matching method with the purpose of reducing resource consumption. However, these methods can＇ t achieve the optimization of service resources and the individual requirements of users. Based on this,this paper studies on it from the perspective of resource scheduling. A service scheduling model is established based on the theory of resource scheduling and feedback network, while service waiting queue is proposed to increase the accuracy of service selection. The delay performance of the model is an- alyzed but using the queue theory. The simulation experiments show that the method proposed can not only relieve the delay on the con- dition of limited service resource and guarantee the fair attainability of requesters,but also meet the individual requirement well.
