摘要
针对目前区块链系统中传播区块消耗大,难以适配无线环境下动态变化网络拓扑的问题,设计了一种基于节点度的无线区块链转发机制,通过复杂网络传播模型确定最低转发下限,在综合考虑能量消耗、吞吐量和安全性的条件下确定最优的转发比例.节点根据自身度指标与转发比例确定转发消息的邻居数量,通过节点邻居的度信息,分布式调整向邻居发送消息的概率,提高了网络中消息的递送效率.仿真结果表明,所提机制性能与洪泛机制相近,但消耗大大减小,各项性能均优于传统的Gossip 机制.
Abstract
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.
