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.
