HF (High Frequency) radio state networking method based on resource distributing policy

Abstract

The invention discloses an HF (High Frequency) radio state networking method based on a resource distributing policy. The network is of a star topologic structure which comprises a central part and peripheral nodes. The central part comprises a network controller and a group of HF transmitters and a group of HF receiver, respectively connected with the network controller. The peripheral nodes comprise a half-duplex HF radio station for executing the steps of uploading service data and control signaling of the peripheral nodes and receiving the commands and the control signaling of the central part. The central part is used for receiving centralized service data and control signaling of the peripheral nodes and issuing the commands and the control signaling of the central part. The network controller controls the work state of the HF transmitters and the HF receivers. The transmitter, the receiver and communication frequency possibly used form a resource pond, and uplink and downlink frequencies are selected through uplink and downlink chains. According to the method provided by the invention, the performance is reliable, and the network has good expandability.

Description

technical field

[0001] The patent of the present invention relates to the field of wireless communication technology networking, in particular to a resource allocation strategy-based HF radio networking method with limited bandwidth. Background technique

[0002] For medium and large-scale HF (High frequency, high frequency) signal acquisition networks, the number U of peripheral nodes will reach hundreds. The general method is to divide the large network into subnets, and then divide the subnets into microgrids. The network topology is as follows: figure 1 shown.

[0003] All peripheral nodes are divided into K groups according to their geographical location and communication conditions, and each group has an average of V=U / K peripheral node members. Each group corresponds to a central pair of transmitters and receivers. Each subnet or microgrid forms a point-to-multipoint (P2MP) star network. In this way, frequencies can be planned for different subnets or microgrids. ...
