Embodiment

[0026] Embodiment: a method for identifying key nodes of a communication network, each node is provided with a transceiver module and a positioning module, and according to the data provided by the positioning module, the V of point A is preset. 0 The node is the starting node. This starting node can connect to X secondary nodes around. Collect the positioning data fed back by each node positioning module until point B, which is the farthest from point A, and point B is V n node; routing node set V={V 0 ,V 1 ,V 2 ,V 3 ...,V n}, n is the number of nodes;

[0027] Routing path from point A to point B:

[0028]

[0029] Priority of key node identification:

[0030] (1)V 0 to V n In between, abnormal nodes are eliminated, and each time the node with the larger connection strength value is selected as the next-level relay node; the purpose is to ensure the effectiveness and stability of the node and provide the basis for efficient routing of the node;

[0031] (2)V 0 ...

Abstract

According to a communication network key node identification method, each node is provided with a transceiving module and a positioning module, a V0 node with a preset distance A is used as an initialnode according to data provided by the positioning module, the initial node can be connected with X surrounding secondary nodes, an X value can be preset, and the maximum X value is 255; the second-level relay node searches for the next-level relay node, and collects the positioning data fed back by each node positioning module every time until reaching the point B farthest away from the point A,and the point B is a Vn node; wherein the routing node set V is equal to {V0, V1, V2, V3..., Vn}, and n is the number of nodes; key node identification is carried out according to a preset priority;wherein the data transmission comprises node parameter presetting, routing node data, connection strength, the number of routing nodes, the sum of distances among the routing nodes and barycentric coordinates of the routing nodes.

Description

technical field [0001] The invention relates to a method for identifying key nodes of a communication network. Background technique [0002] At present, the communication network mainly includes satellite communication and base station communication, and the price of satellite communication is relatively high. There are a large number of operating ships in the coastal waters of our country. Those near the land generally use base station communication, and those beyond the coverage of the base station can only use satellite communication. In fact, most of these operating ships are in the offshore area, not far from the land. It is an urgent problem to solve the problem of organic utilization of offshore operation ships and reducing the cost of data transmission. Contents of the invention [0003] The invention provides a key node identification method of a communication network, and the technical problem to be solved is: to realize effective routing communication and reduc...
