Blockchain Sharding in IEEE 802.11ax Networks

Blockchain technology has extended to secure systems and applications beyond cryptocurrency. Sharding the Blockchain technique increases the system throughput and decreases the delay while enhancing the system security. In this paper, the Medium Access Control protocol for the wirelessly connected Internet of Things devices through IEEE 802.11ax is updated to include the validation process required by Ethereum sharding. The simulation results, where nodes compete to transmit their data, align with the theoretical equations presented in the paper. Lastly, the results show linear enhancement in the performance of the system as the number of shards increases.
