A QoS Architecture for IOT

The application-oriented IoT is an integration of various kinds of technologies, rapidly developing in the globe. To ensure the quality its practical use, it is necessary to research its QoS architecture. We summarize QoS requirements through analysis of characteristic of IoT application service, transmission network, perception in this paper. Then we propose a QoS architecture based on IoT layered structure. This architecture sets QoS agent in lower layers then transmits QoS requirements, trying to guarantee the consistency as well as effectively use the existing QoS mechanisms in every layer.
