Software defined radio node topology deployment method based on multiple attribute decision making

Abstract

Node deployment is the basis for the normal operation of sensor networks. The number and location of sensor nodes deployed in the target area determines the network topology, which will further affect other performance of the sensor network, such as network coverage, connectivity, network construction cost and service life. Therefore, in order to successfully complete the monitoring task, sensor nodes must be properly deployed. This article expounds the establishment principles of the decision-making index system and the problems that should be avoided in the establishment of the decision-making index system, clarifies the nature and classification of the decision-making index, and focuses on the method of determining the decision-making index system. We explained the deterministic attribute index and the normalization method of interval numbers, and classified the normalization method of the deterministic attribute index into [0,1] interval normalization methods and non-[0,1] interval normalization methods. The advantages and disadvantages are analyzed, and the interval attribute value normalization method based on the preference of decision makers is proposed. This article discusses and analyzes the existing schemes of computer-assisted radio node topology deployment in cognitive radio networks. Aiming at the distributed cognitive radio network topology, the behavior model of authorized users is established to achieve the purpose of spectrum prediction, and it is applied to the scheme of pre-spectrum computer-assisted radio node topology deployment.
