Abstract

Blockchain has achieved great success in cryptocurrency for its peculiarities for security and privacy, which are also important in the wireless network. Therefore, there are growing interests in applying blockchain to the wireless network. Wireless Practical Byzantine Fault Tolerance (PBFT) is considered the most applicable consensus mechanism. However, the existing researches and applications are mostly under wired scenarios. In this paper, we investigated the performance of the wireless PBFT network using IEEE 802.11 under unsaturated situations. The performance is evaluated through three metrics: success probability, delay and throughput. Results suggest that there exists a minimum transmission success probability to achieve the end-to-end performance required for the PBFT consensus protocol.
