Distributed performance management of Internet of Things as a service for caregivers

This paper presents a multi-layer distributed performance management model for Internet of Things (IoT) as a service for caregivers. Performance monitoring and control of IoT devices and services are vital functions for e-health systems. Cloud-based IoT systems with centralized data centers further underline the need for distributed management. The main contribution of this paper is a model and prototype implementation that combines low-complexity policy-based and conventional network management with cloud computing paradigm, lightweight IoT protocols, and their data models. A case study on monitoring of heart activity demonstrates interworking between OMA Lightweight M2M protocol, Bluetooth low energy GATT services, and Azure IoT hub cloud platform to enable distributed policy-based performance management.
