[0003] In the prior art, the proxy selection is usually based on the SNR value for statistics. In addition, the proxy selection may be in a non-CSMA time slot, but before the CSMA time slot arrives, a new beacon is received and the neighboring nodes are refreshed, resulting in The proxy node selected at that time is not optimal, which eventually leads to the instability of the link

Embodiment Construction

[0039] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0040] In the HPLC communication networking process, after the slave node STA accesses the network, it selects its proxy node through receiving and evaluating network messages. After selecting the proxy node, it needs to initiate an association request message according to the instructions in the beacon. , after the STA receives the association summary instruction message or the associ...

Abstract

The invention relates to an HPLC communication networking method, and relates to power line carrier communication, and the method comprises the steps of enabling a current node to judge whether to start a network access flow or not according to a preset evaluation strategy; after the network access process is started, selecting one node as a candidate proxy node according to the channel quality and hierarchy of the neighbor nodes and the number of received beacon frames; and generating an association request frame according to the timeout occurrence time of the timer so as to send a network access request to the candidate proxy node. According to the invention, the probability of agent change during network access is reduced, the number of SOF frames in a network optimization stage is reduced, and the overall communication efficiency of a carrier channel is improved.

Description

technical field [0001] The present disclosure relates to the field of power line carrier communication, in particular, to a method, device, storage medium and electronic equipment for HPLC communication networking. Background technique [0002] High-speed power line communication (HPLC for short) is one of the main communication means for the construction of domestic power consumption information collection system. The communication between them completes functional applications such as data collection and cost control. [0003] In the prior art, proxy selection is usually based on the SNR value for statistics. In addition, when proxy selection is performed, it may be in a non-CSMA time slot, but before the CSMA time slot arrives, a new beacon is received and the neighboring nodes are refreshed, resulting in The proxy node selected at that time is not optimal, which eventually leads to link instability. [0004] The information disclosed in this Background section is only ...
