Problems solved by technology

Introducing wireless sensor networks into cognitive radio networks will form a brand new wireless communication platform - cognitive radio system assisted by wireless sensor networks (Mercier B, Fodor V, Thobaben R, et al. Sensor networks for cognitive radio: Theory and system design[J].ICT mobile ANmmit,2008.), the system combines the advantages of sensor networks and the cognitive capabilities of cognitive radio networks. Currently, the combination of sensor networks and radio networks has not been used in the prior art A particularly effective method for locating primary users

Abstract

The present invention discloses a main user positioning method based on sensor and quantum intelligent computing, which is achieved based on a wireless sensor network assisting a cognitive radio network, and includes the following steps: step 1, a network deploy stage; step 2, a positioning information collecting stage; step 3, a distance measurement stage, wherein a data fusion center averages the sampled signal strength as a received signal strength RSS of an anchor node, and estimates the distance between a main user and the anchor node according to the RSS in a lognormal shadow path loss wireless broadcasting environmental model; and step 4, a positioning stage, wherein the positioning problem is converted into an optimization problem, and the optimization problem is solved by using a quantum genetic simulated annealing algorithm, thereby achieving positioning the location of the main user in a two-dimensional space. On the premise that a good positioning performance is ensured, the present invention can achieve the effect of reducing complexity of the algorithm and saving the energy consumption of the battery at the same time; and accurate location information of the main user can be obtained via the positioning method based on the quantum genetic simulated annealing algorithm.

Description

technical field [0001] The invention relates to the cross-application field of cognitive radio and sensor network, in particular to a primary user positioning method based on sensor and quantum intelligent computing. Background technique [0002] With the increase in the application of wireless communication, the number of wireless terminals has increased sharply, and the integration of more and more mobile communication devices and communication services has an increasing demand for higher data transmission rates, which has resulted in the demand for wireless spectrum resources. will reach an unprecedented level, and the available spectrum resources will soon be exhausted. However, the practical problem is that the utilization efficiency of wireless communication spectrum is not high. In the wireless frequency bands currently in operation, there are many "spectrum holes" (unused spectrum). The Federal Communications Commission (FCC) of the United States has measured the sp...
