Efficient Mining Cluster Selection for Blockchain-based Cellular V2X Communications
Cellular vehicle-to-everything (V2X) communication is expected to herald the
age of autonomous vehicles in the coming years. With the integration of
blockchain in such networks, information of all granularity levels, from
complete blocks to individual transactions, would be accessible to vehicles at
any time. Specifically, the blockchain technology is expected to improve the
security, immutability, and decentralization of cellular V2X communication
through smart contract and distributed ledgers. Although blockchain-based
cellular V2X networks hold promise, many challenges need to be addressed to
enable the future interoperability and accessibility of such large-scale
platforms. One such challenge is the offloading of mining tasks in cellular V2X
networks. While transportation authorities may try to balance the network
mining load, the vehicles may select the nearest mining clusters to offload a
task. This may cause congestion and disproportionate use of vehicular network
resources. To address this issue, we propose a game-theoretic approach for
balancing the load at mining clusters while maintaining fairness among
offloading vehicles. Keeping in mind the low-latency requirements of vehicles,
we consider a finite channel blocklength transmission which is more practical
compared to the use of infinite blocklength codes. The simulation results
obtained with our proposed offloading framework show improved performance over
the conventional nearest mining cluster selection technique.Comment: Blockchain, Cellular V2X Communications, Latency, Mining, Vehicular
