Problems solved by technology
Aiming at the insufficient power received by the receiving party due to the propagation attenuation characteristics of the terahertz wave itself, the existing terahertz network medium access control method has the problems of waste of communication resources and low channel utilization, the present invention provides a two-way handshake-based terahertz The medium access control method of the Hertz network, by controlling the stop of the antenna, allocates higher channel throughput to the nodes with high communication requirements; the present invention only needs to use the Rts frame and the Cts frame to establish a channel once to transmit multiple data frames, which is effective Improved utilization of communication resources

Embodiment Construction
[0146] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0147] Such as Figure 5 Shown, the present invention comprises the following steps:
[0148] The first step is to build a network scenario of media access control in terahertz networking based on two-way handshake. The network scenario is as follows: image 3 shown, combined with figure 1 , the size of the network scene is 20m×20m, the AP node is located in the center of the network scene, N edge nodes in the network are randomly distributed within 10m around the AP node, and N is a positive integer. The beam direction of the directional antenna of the edge node always points to the AP node, and the antenna of the AP node scans the terahertz channel at a constant speed to establish a communication link. Taking 6 edge nodes (N=6) in the network as an example, the network model is the same as the background technology 1.

The invention discloses a medium access control method based on two-way handshake, aiming to solve the problems of communication resource waste and low channel utilization. The technical solution is to build a network scenario of medium access control in terahertz networking based on two-way handshake; the AP node and N edge nodes are initialized in parallel; N edge nodes try to perform the first handshake with the AP node in parallel, while the AP node rotates Scan the terahertz wireless channel and monitor the Rts frame sent by the edge node. If the Rts frame from the edge node is received, the antenna of the AP node is aligned with the edge node that sent the Rts frame and stops to complete the first handshake; The edge node sends a Cts frame to complete the second handshake; the edge node and the AP node perform data transmission. The present invention realizes high-efficiency networking and transmission and reception control through two-way handshaking and controlling the stop of the antenna, allocates higher channel throughput to nodes with high communication requirements, and effectively improves the utilization rate of communication resources.
Description
technical field [0001] The invention relates to the field of medium access control in terahertz networking, and in particular to a medium access control method based on two-way handshake. [0002] technical background [0003] Terahertz THz (Terahertz) waves are electromagnetic waves between millimeter waves and infrared light waves, and their frequency range is 0.1THz-10THz. Compared with the low-frequency band of commonly used wireless communication, although the terahertz frequency band has not yet been developed and utilized, but because the terahertz frequency band has a huge unused continuous bandwidth and can support a data transmission rate of tens of Gbps, the terahertz frequency band The frequency band has great potential for development. The terahertz frequency band has great application prospects in the field of short-distance ultra-high-speed wireless network communication, especially in the field of indoor short-distance wireless network communication, which is...
