Embodiment Construction

[0073] In order to make it easier for those skilled in the art to understand the technical solution of this patent, and at the same time, in order to make the technical purpose, technical solution and beneficial effect of this patent clearer, and to fully support the protection scope of the claims, the following is a specific case in the form of this patent. The technical solution of the patent makes further and more detailed descriptions.

[0074] figure 1 Shown is a schematic diagram of the structure of the THz-WPAN terahertz wireless personal area network. The network contains a central control node PNC and multiple nodes DEV. Among them, the PNC periodically broadcasts beacon frames to provide basic networking information. Data is also transmitted between DEVs and between DEVs and PNCs.

[0075] THz-WPAN divides the network running time into countless superframes, and the PNC can automatically adjust the length of the superframe according to the amount of data. The speci...

Abstract

The invention discloses an adaptive edge node information reporting method for THz-WPAN, belonging to the technical field of THz-WPAN. The present invention introduces the concept of an edge node into the communication of the cross-terahertz wireless personal area network, which helps to find out the cause of the interference problem encountered during the N-CTAP period, and provides a solution for solving the interference. At the same time, the present invention proposes an adaptive edge node information reporting method. When a node finds itself to be an edge node, the node can efficiently and timely report the node type information to the PNC of its personal area network without adding additional control overhead. In this way, if the PNC finds that a DEV is an edge node, it can take measures on time slot allocation to reduce or even eliminate the interference between PANs brought by the edge node.

Description

technical field [0001] The present invention relates to the technical field of THz-WPAN, in particular to an adaptive edge node information reporting method for THz-WPAN, which helps to reduce or eliminate the inter-PAN interference caused by edge nodes. Background technique [0002] Terahertz wireless personal area network (THz-WPAN) is a wireless ad hoc network using THz waves as the carrier. In this network, each wireless personal area network (WPAN) is composed of several DEV nodes, among which a node with a higher priority competes to become the PNC of the network, and this node provides basic networking information. A node located in the overlapping area of ​​two WPANs is called a bridge (bridge), which coordinates and synchronizes the two WPANs by forwarding heartbeat messages. [0003] THz-WPAN divides the network running time into multiple superframes, and the PNC automatically adjusts the length of the superframe according to the amount of data. The super frame ...
