As a key technology to realize smart services of Internet of Things (IoT), network virtualization technology can support the network diversification and ubiquity, and improve the utilization rate of network resources. This paper studies the service-oriented network virtualization architecture for IoT services. Firstly the semantic description method for IoT services is proposed, then the resource representation model and resource management model in the environment of network virtualization are presented. Based on the above models, the service-oriented virtual network architecture for IoT is established. Finally, a smart campus system is designed and deployed based on the service-oriented virtual network architecture. Moreover, the proposed architecture and models are verified in experiments.
