Investigations on Communication and Management Techniques for Electric Internet of Things Applications in Smart Grid

With the rapid advancement of Smart Grid services as well as the technology of Internet of Things (IoT), current electric communication network faces the challenges of supporting the emerging service communication requirements, i.e., wide coverage and efficient management, of distributed power, micro-grid, interactive utility usage. This paper investigates into the communication and management techniques for electric IoT applications, including comparation of various terminal access technologies as well as several telecommunication technologies and analysis of the working mechanism of typical IoT communication protocols such as MQTT (Message Queuing Telemetry Transport) and CoAP (Constrained Application Protocol). Then, the different electric IoT communication requirements are mapped with various access communication technologies as well as corresponding protocols to achieve the full coverage and interconnected data transmission. Furthermore, an integrated design of communication management architecture, pertinent protocol parsing and conversion techniques are proposed to enable real-time monitor and management of vast number of communication modules of electric IoT terminals.
