Embodiment Construction

[0029] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0030] figure 1 The flow chart of the cognitive radio node networking method provided by the preferred embodiment of the present invention is shown. Such as figure 1As shown, the cognitive radio node networking method provided by the preferred embodiment of the present invention includes steps S1-S3.

[0031] Step S1: Unauthorized user node Ui creates available channel set Mi and neighbor information table Ni, and generates default frequency hopping sequence Si.

[0032] Specifically, the cognitive radio node networking method provided by the present invention is suitable for single-hop networks, and is mainly aimed at static networks with fixed node locations. Before the unlicensed user node Ui ...

Abstract

A cognitive radio node networking method comprises the following steps that: an unlicensed user node Ui establishes an available channel collection Mi and a neighbor information sheet Ni and generates a default frequency hopping sequence Si; the Ui uses Si frequency hopping to search an unlicensed user node Uj, obtains a neighbor information sheet Nj of the Uj and combines the Nj with the Ni, and then judges if nodes having no communication with the Ui exists in the combined neighbor information sheet Ni; and if so, the Ui establishes a deviated frequency hopping sequence Wi, selects a time slot and a channel of a node having no communication in the Ni, adds the selected time slot and channel into the Wi, and repeats the operation until all the time slots in the Ni are searched; and the Ui replaces the default frequency hopping sequence Si in the Ni by using the deviated frequency hopping sequence Wi and carries on the frequency hopping search by using the Wi.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for networking cognitive radio nodes. Background technique [0002] In recent years, the wireless communication industry has experienced rapid development, and wireless spectrum is an indispensable and precious resource for wireless communication. A large number of studies at home and abroad have shown that some unlicensed frequency bands such as industrial, scientific, and medical (ISM) frequency bands and licensed frequency bands for mobile communications are overcrowded, while a large number of other licensed frequency bands are often idle. In order to solve the problem of irrational use of spectrum resources, researchers proposed the concept of Dynamic Spectrum Management (Dynamic Spectrum Management). Compared with the existing fixed spectrum management method, the dynamic spectrum management mechanism can effectively match spectrum resources with spec...
