A Mobile Edge Computing Enabled Spectrum Blockchain for the Internet of Spectrum Devices

To achieve secure and immutable spectrum data monitoring and sharing, and further to realize accurate and reliable spectrum strategy customization, a mobile edge computing (MEC) enabled spectrum blockchain is developed for the internet of spectrum devices (IoSD). Specially, a three-stage consensus mechanism is designed to achieve secure and immutable spectrum data monitoring and sharing, and spectrum blockchain employs the edge-deployed personal wireless device to realize efficient storage of massive spectrum data and quickly response of spectrum strategy customization. The malicious behaviour of spectrum data falsification is employed as Byzantine attack to evaluate the security performance of the proposed MEC-enabled spectrum blockchain. Numerical simulations show the consensus mechanism identify the malicious behaviours with high probability of detection under a variety of scenarios.
