Architecture, Integrated Gateway Design, And Performance Evaluation for High Concurrency Access of Power Internet of Things

Abstract

Power Internet of things (IoT) is deemed as a promising network platform with widely deployed infrastructure to boost efficient information delivery in the power grid. Due to the long history of the mature power grid and increased requirements from various industries, the architecture of power IoT should be carefully investigated. Specifically, a large number of end devices in the power grid are required to simultaneously report their sensed information to the management side. However, there are few works related to the uniform communication mechanism to support various devices made by different manufacturers. In this paper, we study the architecture of power IoT for high concurrency access. For each layer of power IoT, we study its fundamental structure and functionality. Moreover, according to the architecture of power IoT, we propose an integrated gateway to support multiple end device simultaneous access. The simulation results verify that the proposed gateway can work well in different network traffic and communication protocols.
