Embodiment Construction

[0014] The technical solution of the present invention is further described below in conjunction with the embodiments, but the scope of protection is not limited to the above.

[0015] The method to improve user security in cognitive radio network includes the following steps:

[0016] (1) Set the transmit power of authorized users and unauthorized users in the cognitive radio network to a fixed value;

[0017] (2) Authorized users make requirements based on their existing security. If unauthorized users can meet the requirements of authorized users, they are allowed to access the authorized spectrum;

[0018] (3) Unauthorized users reach a stable state by merging or splitting alliances: Unauthorized users form an initial multiple disjoint alliances. If several alliances are merged into a new alliance, each user will not get The channel capacity is less than before, and at least one unlicensed user group can obtain more channel capacity, then these alliances are merged into a new alli...

Abstract

The invention discloses a method for improving user security in a cognitive radio network, which includes the following steps: (1), setting the transmission power of authorized users and non-authorized users in the cognitive radio network to a fixed value; (2) Authorized users put forward requirements according to their existing security; (3) Unauthorized users achieve a stable state by merging or splitting alliances; (4) Select an alliance with the largest sum of channel capacity to allow (5) The unlicensed user group accessing the licensed spectrum accesses the licensed spectrum in a time-segment and time-sharing manner. The beneficial effect of the present invention is: the security of the authorized user is considered rather than the channel capacity, the security of the authorized user is improved, and the secure communication of the authorized user is used as the main reference standard, and more unauthorized users are realized The purpose of accessing the licensed spectrum.

Description

Technical field [0001] The invention relates to a method for improving user safety in a cognitive radio network, and belongs to the technical field of network media technology. Background technique [0002] With the increase of network traffic, the concept of cognitive radio network was proposed to improve the spectrum utilization. There are authorized users and unlicensed users in cognitive radio networks. It is one of the commonly used methods to increase the utilization rate of the spectrum by allowing unlicensed users to use the spectrum of authorized users in some specific situations. [0003] In cognitive radio networks, there are two ways for unlicensed users to access the spectrum, the first is called overlay, and the second is called underlay. In the overlay mode, unlicensed users detect whether there are authorized users on the licensed spectrum. If it is detected that no authorized user uses its authorized spectrum, the unauthorized user accesses the network and occupi...
