Optimal target coverage method for heterogeneous sensor network based on quantum brainstorming

Abstract

For the disadvantages that the existing method is poor in optimizing result and slow in convergence speed and loses efficacy while the joint perceptive probability is relatively high when the problem of optimal equivalent working sensor distribution in target coverage is solved, the invention provides a novel optimal target coverage method for a heterogeneous sensor network. By means of the optimal target coverage method provided by the invention, the disadvantage that the current brainstorming optimization algorithm cannot be applied to a discrete problem can be solved; and the application range of the brainstorming algorithm is expanded. A simulation result shows that: compared with the existing classical target coverage method, the convergence speed and the convergence precision of the optimal target coverage method in the invention are relatively superior; therefore, the effectiveness of the optimal target coverage method in the invention is proved; under same conditions, when the joint perceptive probability constraint is relatively strict, the traditional method can lose efficacy; but, the method in the invention still is feasible. According to the optimal target coverage method provided by the invention, scheme exchange in a brainstorming process is reflected in the generation mode of a new scheme in a fusion manner; and, compared with scheme exchange of the original brainstorming algorithm, the scheme exchange is relatively wide, and is closer to a real brainstorming process.

Description

technical field [0001] The invention relates to a method for optimal target coverage of a heterogeneous sensor network based on quantum brainstorming, and the method relates to the field of coverage control of the heterogeneous sensor network. Background technique [0002] Coverage control is an important research content of heterogeneous sensor networks. In heterogeneous sensor networks, the technology that satisfies user perception needs through optimal allocation of space resources is called coverage control technology. It is the basic technology of the heterogeneous sensor network, which can directly reflect the perceived service quality of the heterogeneous sensor network to the environment. According to different configuration methods of heterogeneous sensor network nodes, that is, whether nodes need to know their own location information, coverage control can be divided into two categories: deterministic coverage and random coverage. According to different objects a...
