Embodiment Construction

[0023] refer to figure 1 , the present invention is realized based on a system composed of a directional antenna and a centerless self-organizing network, and specifically includes the following steps:

[0024] (1) Binary number each node in the non-central self-organizing network;

[0025] The number adopts binary number form. If the number of nodes is m, the minimum number of digits is taken, so that 2 s ≥m; if the binary number of the node is less than s digits, the high digits will be filled with zeros to make the digits equal to s.

[0026] (2) The node obtains the number of beams of the directional antenna according to the main lobe angle of the lobes of the directional antenna, determines the number of scanning directions N of the directional antenna, N is a natural number greater than 1, and obtains the number of the scanning direction of the directional antenna, and the directional antenna rotates All scan directions are one scan cycle;

[0027] Set a certain secto...

Abstract

The invention discloses a novel neighbor finding method based on a directional antenna. The neighbor finding method comprises the following steps that binary system numbering is carried out on nodes, the antenna scanning direction is numbered, one node determines a receiving and sending mode according to the binary system number of the node, determines the scanning sequence according to the receiving and sending mode and carries out scanning at the neighbor finding stage according to the scanning sequence, and if a pair of receiving and sending nodes successfully come to a handshake protocol, it is shown that the neighbor finding process is successful. The novel neighbor finding method solves the problem of neighbor finding of the non-central networking under the condition of the directional antenna, the advantages of the high interference resistance and high space reused ratio of the directional antenna can be exploited to the full the flexible characteristic of entering and existing the network of the non-central networking are fully utilized, and the method has wide application prospects.

Description

technical field [0001] This patent discloses a neighbor discovery method based on a directional antenna, which is suitable for a centerless self-organizing network under the condition of a directional antenna. Background technique [0002] For the application of directional antennas in wireless ad hoc networks, although it can improve the overall performance of the network, it will also bring a series of problems, such as the problem of hidden terminals and exposed terminals, the generation of deaf nodes, and the problem of effective neighbor discovery. This is challenging for the design of wireless network protocols with directional antennas, especially the design of neighbor discovery methods. Contents of the invention [0003] The problem to be solved by the patent of the present invention is to provide a neighbor discovery method suitable for a centerless networking under the condition of directional antennas. [0004] A novel neighbor discovery method based on direct...
