Wireless Blockchain Forwarding Mechanism with Node Connectivity
Aiming at the problem of the large propagation consumption in the current blockchain sys-tem which is difficult to adapt to the dynamic network topology in a wireless environment,a wireless blockchain forwarding mechanism based on node connectivity is designed.First,the minimum forwarding proportion is determined through the complex network propagation model.The optimal forwarding pro-portion is determined by the utility function which takes the energy consumption,throughput performance and security performance into consideration.The number of neighbors to forward messages is determined based on the sending node connectivity and forwarding proportion.Second,the probability of sending mes-sages to neighbors is adjusted through the connectivity of the neighbor,which improves the efficiency of message delivery in the network.The simulation results show that the performance of the proposed mech-anism is similar to the flooding mechanism,but the consumption is greatly reduced,and all the perform-ance of d-Gossip is better than that of Gossip.
