Design and implementation of a WiFi sensor device management system

Abstract

In this paper, we described the design for a device management system of 802.11 based sensors. In this management system, the management functions are separated from IoT services and put into a logically centralized management entity. The management entity manages the sensors through a lightweight management protocol which is based on IETF CoAP protocol. In addition, the management entity provides north bound interface to IoT services. According to the design, we have implemented a PoC system which includes the 802.11 based sensors, the management entity and a sample IoT service. The PoC system has proved the feasibility and effectiveness of our design.
