Blockchain and Communication Networks

Special Issue on “Blockchain and Communication Networks”

With the boom of new technologies and applications, e.g., Internet of Things, big data, and artificial intelligence, a deluge of devices are being connected to the network and are generating a large amount of data. Data collection, processing and analysis are the essential processes to help people gain valuable information and make smart decisions, and make devices more intelligent. The underlying communication network is thus confronted with unprecedented challenges. Along with the increase in devices, managing these devices in the existing centralized model will bring great challenges to the infrastructure construction, maintenance, and management of the communication network. In addition, the current technology/protocol in communication networks cannot effectively protect the security and privacy of user data, and the use of collected data is beyond the control of the user. Internet users and companies therefore worry about the privacy of their data and are not willing to provide valuable data for processing and analysis.

Blockchain enables transparent interactions of different parties in a more secure and trusted way. It is a promising technology that can simplify the management of trusted information over communication networks. Given that the blockchain is trustworthy, secure and cannot be tampered with, more data are likely to be provided over the communication networks. The traceability of blockchain allows data to be retained on the blockchain from every step of collection and transaction, to endorse the quality of the data and to ensure the correctness of data analysis and mining. The decentralization of blockchain also provides a way for device management in the communication networks. It can help devices understand each other (knowing the relationships between different devices). However, employing blockchain mechanisms in communication networks still has some technical challenges and limitations. For example, how to efficiently and reliably achieve interoperability between different blockchains, and how to improve the efficiency and reduce the resource overhead when using blockchains still need to be studied and addressed. In addition, blockchain technology is still in its infancy and might face new types of attacks and new challenges.


To address these issues and opportunities, this special issue invites original research that investigates blockchain technologies and decentralization mechanisms for communication networks. The topics of interest include, but not limited to:

  • The design and implementation of test bed and infrastructure of blockchain
  • Blockchain and network big data
  • Blockchain and the Internet of Things
  • Blockchain in future network architecture
  • Blockchain in next generation mobile communication networks
  • Design, optimization and improvement of network protocols based on blockchain
  • Encryption technology in blockchain
  • Identification technology and access control techniques in blockchain
  • Cross-chain communication protocols
  • Database for blockchain
  • Data consistency in blockchain
  • Flow characteristics analysis
  • The analysis and modeling of the efficiency and cost of blockchain
  • Decentralized schemes for communication networks
  • Privacy enhancement technology in blockchain
  • Accountability in blockchain
  • Security of blockchain
  • Policy and law research about blockchain
  • Blockchain for data collection and analysis in communication networks
  • Blockchain for communication network management
