- Abstract
To meet the requirement of the precisely spectrum sharing triggered by large-scale and ultra-dense deployment of mobile internet and internet of things, a framework based on blockchain technology for networking the massive personal wireless devices to form the Internet of spectrum device (IoSD) was proposed. The architecture of cloud with edge computing was proposed as the architecture of IoSD, which consists of spectrum management server, mobile base station, and personal wireless devices. The mechanism of spectrum data acquisition, spectrum block appending, spectrum data transmission, and spectrum sensing incentive, consist of basic operational mechanism of IoSD. The distributed consensus mechanism, including fusion consensus among sensing-nodes, verification consensusamong checking-nodes, and confirmation consensus among head-nodes, was applied to determine whether the spectrum data was falsified by the Byzantine attack of malicious sensing-nodesunder the hypothesis test of certain confidence. The simulation results show the effectiveness and robustness of proposed distributed consensus mechanism in preventing spectrum sensing data falsification by the malicious nodes.
