Networking method and system for power line carrier and wireless converged communication

Abstract

The invention discloses a networking method and a networking system for power line carrier and wireless converged communication. The networking method comprises the steps of: firstly, searching lower-level nodes step by step from a central node until all the terminal nodes complete present-level network layering, and recording signal-to-noise ratio information of a power line carrier channel between each node and the upper-level node thereof and signal-to-noise ratio information of a wireless channel between the node and the upper-level node thereof by means of the node in the searching process; selecting a cluster head node of each level according to the signal-to-noise ratio information and connectivity information of the nodes; creating a cluster; and selecting an inter-cluster relay node by means of the cluster head node of each level according to the signal-to-noise ratio information between the cluster head node and a cluster head node of an upper level, and completing the networking of the clusters. The networking method and the networking system for power line carrier and wireless converged communication can realize quick and reliable networking of a power line carrier andwireless converged communication network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a networking method and system for power line carrier and wireless integrated communication. Background technique [0002] Power terminal communication technology mainly includes broadband / narrowband power line carrier communication, micropower wireless communication, power wireless private network and power EPON and other technologies. Among them, the power line communication technology and the wireless communication technology have good complementarity, and the close combination of the two can effectively improve the coverage and reliability of the communication service of the power distribution and consumption terminal compared with a single communication method. However, the difference between the power line channel and the wireless channel not only increases the integration difficulty of the two communication methods, but also makes the network of power line an...

Problems solved by technology

However, the difference between the power line channel and the wireless channel not only increases the integration difficulty of the two communication methods, but also makes the network of power line and wireless converged communication more complicated. Therefore, for the reliability of power line and wireless converged communication, research on power line and wireless The integrated communication networking method is particularly important. At present, there are many independent power line communication networking methods and independent wireless communication networking methods, but there is no specific research on the power line and wireless integrated communication networking method.
