Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing.

[0039]The invention combines the block chain technology with the UAV-assisted Internet of Things system, and proposes a UIB system to encourage UAVs to collect sensor data.

[0040] The present invention proposes a PoVD consensus mechanism based on the UIB system to verify the authenticity of the data and ensure the fairness of rewards.

[0041] The following is a detailed introduction to the UIB system and the PoVD consensus mechanism.

[0042] 1. The following describes the UIB system from two aspects of physical architecture and logical architecture.

[0043] UIB system network architecture such as figure 1 As shown, in the Internet of Things scenario, most of the sensor nodes with fixed positions only have limited power and have certain computing and communication capabilities. In the UIB system, the UAV moves over the network area, and the data collected by the sens...

Abstract

The invention discloses an Internet of Things architecture based on a block chain and a verified data proof consensus method. According to the method, the characteristics of the block chain and the Internet of Things are combined. An unmanned aerial vehicle assists the Internet of Things in data collection, under the condition that high-speed wireless link coverage does not exist in a remote area,data can be effectively transmitted through the unmanned aerial vehicle, a block chain technology is introduced, the unmanned aerial vehicle is excited to collect the data in the form of cryptocurrency, and the unmanned aerial vehicle serves as a block chain node to upload the collected original sensing data to the block chain. Meanwhile, the sensor node calculates the hash value of the collectedoriginal sensing data and uploads the hash value to the block chain through the macro base station. In addition, the invention also provides a verified data proof consensus mechanism, the authenticity of the data is verified, and meanwhile, the fairness of rewards is ensured.

Description

technical field [0001] The invention belongs to the field of block chain technology, and takes the block chain-based Internet of Things architecture and consensus algorithm as the research object, and on this basis, proposes a block chain-based Internet of Things architecture and verified data proof consensus method. Background technique [0002] In recent years, the continuous improvement of drone technology has attracted widespread attention from various industries. The application range of drones has developed from military, agricultural and other fields to various aspects of the Internet of Things. For example, drones equipped with communication facilities serve as air base stations for Ground communication equipment provides communication services, and assists sensor nodes in providing caching services as IoT nodes. Data collection based on UAV nodes in the Internet of Things can balance network energy consumption and prolong network life cycle. IoT devices, especially...
