Control Singaling Scheme of Upstream Data Transmission for Power Internet of Things

Abstract

In order to solve the problems of long copy time and low success rate in the application of high-speed power line communication and wireless dual-mode fusion network, this paper proposes a data transmission upstream signaling technology, introduces the idea of “connection-oriented”, uses signaling scheme from the beginning to the end of data transmission, and establishes a “end-to-end” stable transmission path and routing for data upstream transmission. The parameters of bandwidth, time slot and signal power are set by each intermediate node through which the transmission path is interactively terminated by signaling after all data frames have completed the upstream transmission. Simulations and field tests show that the method can ensure the reliability of data upstream transmission in dual-mode network, improve the success rate of communication and reduce communication delay.
