A medium access control method for terahertz networking based on one-way handshake

Abstract

The invention discloses a medium access control method based on one-way handshake, aiming to solve the problems of high packet loss rate and unguaranteed service quality. The technical solution is to build a network scenario of medium access control in terahertz networking based on one-way handshake; the AP node and N edge nodes are initialized in parallel; the antenna of the AP node rotates 360° at a rate of The nodes take turns to perform the first two handshakes; the antenna of the AP node rotates again at a rate of r turns / s, and performs the third handshake with the i-th edge node according to the source address of the first element of the QI table. After the handshake, the antenna of the AP node is Accurate the i-th edge node and stop; the i-th edge node communicates with the AP node until the data transmission of the i-th edge node is completed; the antenna of the AP node restarts and rotates, and communicates with the i+1-th edge node. The invention effectively reduces the packet loss rate and ensures the service quality by controlling the stop of the antenna.

Description

technical field [0001] The invention relates to the field of medium access control in terahertz networking, in particular to a medium access control method based on one-way handshake. [0002] technical background [0003] Terahertz (Terahertz) waves are electromagnetic waves located 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, because the terahertz frequency band has a huge unutilized continuous bandwidth, it can support the data transmission rate of tens of Gbps, so the terahertz frequency band has not been exploited yet. 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 wireles...

Problems solved by technology

Aiming at the problem that the reception power of the receiving party is insufficient due to the propagation attenuation characteristics of the terahertz wave itself, the existing medium access control method of the terahertz network has a high packet loss rate and the problem that the quality of service cannot be guaranteed. The present invention provides a unidirectional The medium access control method of terahertz networking based on handshake, the receiver initiates the communication, collects the transmission request of the sender, and allocates the channel time according to the transmission request of each edge node, effectively avoiding the edge nodes from competing for the channel due to disorder The resulting packet loss effectively reduces the packet loss in communication, thereby ensuring the quality of service
