AHP-based QoS Evaluation Model in the Internet of Things

The Internet of Things (IOT) has recently become popular to emphasize the vision of a global infrastructure of networked physical objects. A QoS model according to improved Analytical Hierarchy Process (AHP) is proposed. The resource state, the user preferences and device performance are taken into consideration in order to improve the reasonableness of the QoS evaluation model. A simulation is performed to verify the study results, which reflects that the service controller in the framework that can promptly evaluate available services and select the best service for users with the model.
