Abstract

The invention discloses a method for adaptively adjusting the number of time slots in a beacon period. In the process of multi-site network access, STAs are divided into two types according to whether they can only be used as terminal nodes, and the required load capacity in a beacon period is calculated. The theoretical minimum value n of the number of station time slots for broadcast sending discovery beacons, by judging whether there is a network access request timeout, automatically adding and subtracting the number of station time slots for broadcast sending discovery beacons, can improve the division of beacon time slots in the beacon period , so that in the entire beacon period, the proportion of data transmission increases, and the efficiency of data transmission is improved.

Description

technical field [0001] The invention belongs to the technical field of broadband power line communication, and in particular relates to a method for adaptively adjusting the number of time slots in a beacon period. Background technique [0002] PLC (Power Line Communication) refers to a communication method using power lines as the transmission medium. It is mainly used in remote automatic meter reading, automatic control of distribution network, internal interconnection of homes, intelligent communities and the last mile network of multimedia communication. Access, etc., has the characteristics of fast construction, low investment, and no need for indoor wiring. In recent years, the development of BPL (Broadband over Power Line, broadband power line communication) related technology has improved the data transmission rate of power line communication, especially the development of orthogonal frequency division multiplexing technology has enabled high-speed PLC to be realized...
