一种面向物联网数据交易的高效PCN路由策略

Efficient Routing Strategy for IoT Data Transaction Based on Payment Channel Network

为了提高物联网数据交易的效率,提出了一种基于付费信道网络(Ppayment Channel Network,PCN)的高效路由策略。该策略从网关选择和大额交易拆分两个方面入手来完善PCN网络的缺陷。通过计算不同网关的支付和接收资金流量比率来选择合适的网关进行交易,以保证网络的平衡,增加了网络的稳定性。为了解决大额交易时信道容量不足的问题,将单笔交易拆分成多个交易单元,并通过多信道均衡算法来进行路径选择,减少了链上交易次数,提高了网络的交易效率。仿真结果表明,该方案拥有较高的交易成功率和更低的交易时延。

In order to improve the efficiency of data transactions in Internet of Things,an efficient routing strategy based on payment channel network(PCN)is proposed.This strategy improves the defects of PCN network from two aspects:gateway selection and large-value transaction splitting.By calculating the payment and receiving fund flow ratios of different gateways,the appropriate gateways are selected for transactions to ensure the balance of the network,which increases the stability of the network.In order to solve the problem of insufficient channel capacity in large-value transactions,a single transaction is split into multiple transaction units,and path selection is performed through a multi-channel equalization algorithm,which reduces the number of transactions on the chain and improves the transaction efficiency of the network.Simulation results show that the program has a higher transaction success rate and lower transaction delay.
