The invention provides a crowd-sourcing spectrum sensing method and system based on an alliance chain, and a storage device. The method comprises the following steps: registering identity information of nodes joining the alliance chain; obtaining a sensing task issued by a sensing task requester; obtaining response information of the sensing user to the sensing task issued by the sensing task requester on the alliance chain; allocating the sensing task issued by the sensing task requester on the alliance chain to the responding sensing user; obtaining spectrum data collected by the sensing users distributed with the sensing tasks; generating a sensing result according to the spectrum data collected by the sensing user with the distributed sensing task; verifying the quality of the perception result to obtain a quality verification result; calculating rewards of the corresponding perception users to obtain transaction information; and forming the transaction information into blocks and adding the blocks into the alliance chain. According to the method and system, the problems of single-point failure, hostile attack, node data counterfeiting and sensing node privacy leakage in a traditional crowd-sourcing sensing system are solved.
Description
technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a method, system and storage device for crowd intelligence spectrum sensing based on alliance chain. Background technique [0002] The rapid development of wireless communication technology has caused a sharp increase in wireless devices, making wireless spectrum resources very scarce. At present, spectrum resources are authorized by a fixed allocation method, so the spectrum utilization efficiency is very low and extremely unbalanced, and the cognitive radio system emerges as the times require. Cognitive radio can sense the system environment, find idle spectrum, and perform dynamic spectrum allocation, which can effectively improve the efficiency of spectrum utilization. The premise of cognitive radio implementation lies in spectrum sensing technology. Single-node sensing is greatly affected by shadow effects and deep fading, and the sensing results are unreliab...
