In this paper, we model and analyze the characteristics of a blockchain enable wireless Internet of Things. Blockchain is considered a vital technology for the development of a secure and trusted Internet of Things (IoT) in next-generation networks. However, the current blockchain architecture usually requires extensive computing power and storage capacity, which hinders its deployment in a wireless IoT network. Taking into account these limitations, we establish an analytical model for a lightweight blockchain architecture tailored to wireless IoT networks, and investigate the transmission success probability of the proposed model. We then capture the relationship between transmission link condition (e.g., the transmission success probability) and the success rate of Raft consensus inside the blockchain network. Our analysis shows that the Raft consensus success rate is a function of the transmission link condition and the number of network nodes. Furthermore, when we increase the number of nodes, the consensus success rate displays different tendencies with regard to uplink and downlink transmission link conditions. In particular, consensus success increases when the combination of transmission link probabilities on uplink and downlink is greater than 1/2, and decreases in the opposite scenario. The authenticity of our analysis is verified via simulations.
