Problems solved by technology

The shortage of frequency resources is an important factor restricting the development of wireless communication technology. Although the electric power industry has some frequency points in the dedicated 230MHz frequency band, it cannot fully meet the needs of wireless transmission of existing business data. The shortage of frequency resources also limits the performance of its communication system.

Embodiment Construction

[0043] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0044] The system architecture diagram of the power cognitive wireless network defined in the present invention is as follows figure 1shown. The power cognitive wireless network includes power cognitive base stations, power cognitive nodes, and cognitive coordination centers, and its available frequency resources can come from power McWiLL communication networks, power WiMax communication networks, power 230MHz private networks, and ISM frequency bands (such as WiFi network ) in one of the networks or idle frequency resources in multiple networks. In the figure, the power cognitive base station is responsible for wireless management within its coverage area, including the control and management of cognitive users, the fusion and judgment of cognitive results, the allocation of dynamic frequency resources, frequency swit...

Abstract

The invention relates to a frequency allocation method of an electric power cognitive wireless network. The electric power cognitive wireless network includes an electric power cognitive base station, electric power cognitive nodes and a cognitive coordination center, the power allocation method is realized directed at the electric power cognitive base station and the electric power cognitive nodes and based on fairness and frequency utilization rate. Frequency resources available to the electric power cognitive wireless network come from idle frequency resources of one or more networks of an electric power McWiLL communication network, an electric power WiMax communication network, an electric power 230MHz private network and public free ISM frequency bands. The method not only considers access fairness of the cognitive nodes under electric power application conditions, but also provides an allocation algorithm with a high frequency utilization rate, thereby satisfying a requirement for access of more nodes, and realizing efficient utilization on the basis of frequency resource allocation fairness.

Description

technical field [0001] The invention relates to a distribution method of power system communication technology, in particular to a frequency distribution method of a power cognitive wireless network. Background technique [0002] As an important supplement to the electric power wired communication network, the electric power wireless communication network is an important part of the smart grid communication network, and has played an important role in the development of the smart grid. The shortage of frequency resources is an important factor restricting the development of wireless communication technology. Although the electric power industry has some frequency points in the dedicated 230MHz frequency band, it cannot fully meet the needs of wireless transmission of existing business data. The shortage of frequency resources also limits the performance of its communication system. . The cognitive radio network uses frequency sensing technology to opportunistically use the ...
