A NETworking scheme for an Internet of Things Integration Platform

摘要

The Internet of Things (IoT) enables several heterogeneous devices, sensors, wearables, appliances and many other objects to inter-communicate and provide support for heterogeneous services. An IoT network needs to enable exchange diverse data types including multimedia and sensor data and be capable of handling a large number of IoT objects offering services at high quality levels. This paper proposes NETSMITS, an innovative IoT solution which improves the performance and quality of IoT services. It uses a layered architecture that consists of IoT objects, which provide diverse services including video applications and CCTV monitoring, smart gateways, which support IoT object network connectivity and a cloud-deployed IoT Integration Platform (ITINP) employed for resource management. NETSMITS introduces an innovative algorithm which uses Quality of Service (QoS) and service relevance metrics in order to efficiently cluster the inter-communicating IoT objects, attach them to the most suitable smart gateway and improve the performance of their services. Simulation-based testing shows how NETSMITS outperforms an existing state of the art solution for delivering video services in terms of QoS metrics such as packet loss.
