Problems solved by technology

[0003] Most of the existing cognitive technologies focus on research on point-to-point communication, focusing too much on the technical research of various perception methods and cognitive decision-making under point-to-point links. However, how to carry out the application of cognitive technologies under self-organizing networks Relatively poor, especially less research on the engineering implementation of cognitive technology combined with communication systems

Embodiment Construction

[0013] 1. Cognitive Architecture

[0014] The present invention adopts the cognitive architecture of distributed sensing and centralized decision-making, and cognitive users share information with other users, each node can grasp the sensing information of all nodes, and the nodes themselves can fuse and judge the availability of spectrum without setting up a dedicated fusion center .

[0015] The present invention is designed according to the self-organizing network structure. There is no base station and no special fusion center. It uses distributed to realize cooperative spectrum sensing and detection. It is only necessary to select a logical central node to initiate the frequency for the consistency of spectrum decision-making and frequency switching execution. switch, such as figure 1 As shown in the figure, all cognitive nodes 1 to 4 in the figure perform perception and exchange sensing information with each other, and cognitive node 3 can be used as a logic central nod...

Abstract

The invention discloses a cognitive system based on combination of active sensing and passive sensing for a self-organizing network. The system comprises a cognitive engine and a communication module,wherein the communication module fulfills physical functions of a communication protocol stack; the cognitive engine comprises spectrum sensing and a dynamic spectrum access control center; the spectrum sensing completes the active sensing and the passive sensing of electromagnetic environment information; and the dynamic spectrum access control center comprises a scheduler, a time slot manager,a frequency controller, a frequency decision maker, and a convergence processor. The system provided by the invention is applied to the self-organizing network, and has the advantages that the invulnerability, communication reliability, self-adaptability and interference resistance of the network can be improved; and a specific engineering implementation method for the promotion and application ofcognitive transmission technologies in the self-organizing network is provided, so that a certain foundation for researches and discoveries in intelligent wireless communication networks is laid, andcertain reference value for future non-configured, autonomous and intelligent network communication is achieved.

Description

technical field [0001] The invention relates to a cognitive system based on combination of active and passive perception suitable for ad hoc networks. Background technique [0002] Cognitive radio technology is based on software radio. Through real-time sensing of the electromagnetic environment and real-time intelligent adjustment of transmission parameters, it can effectively avoid interference and achieve highly reliable communication and efficient spectrum utilization. Cognitive radio can meet the requirements for effective communication in a rapidly changing, complex and highly confrontational environment, and improve the reliability and transmission efficiency of wireless communication. Cognitive radio provides effective measures to solve the problem of communication anti-interference, so cognitive radio technology has been favored by all parties once it was proposed. [0003] Most of the existing cognitive technologies focus on research on point-to-point communicatio...
