基于IOTA区块链的一种新型Tips选择算法的研究

A New Tips Selection Algorithm Based on IOTA Blockchain

区块链作为构建6G价值互联网的重要基础设施,已经广泛应用于各个领域,而专为物联网设计的IOTA区块链,共识时间短,零交易费,吞吐量大等优点广泛用于大规模物联网中。然而,在现有的IOTA区块链中,Tips选择选择算法并没有考虑用户的时间敏感度需求,会产生较多的孤儿,不能很好的为用户服务,因此本研究综合考虑孤儿的数量,用户的时间敏感度,设计了新的Tips选择算法。仿真和分析结果表明:本研究提出的算法明显降低了孤儿的数量,更好的满足不同时间敏感度用户的需求。

As an important infrastructure for 6G Internet,blockchain has been widely used in various fields.Particularly,the IOTA blockchain designed for the Internet of Things(IoTs),which has the advantages of short consensus time,zero transaction fees,and large throughput,are widely used in large-scale IoTs.However,in the existing IOTA blockchain,the tips selection algorithm does not consider the time sensitivity needs of users,which will produce more orphans and cannot serve users well.Therefore,this paper comprehensively considers the number of orphans and the time sensitivity of users and designs a new tips selection algorithm.Simulation and analysis results show that the algorithm proposed in this paper significantly reduces the number of orphans and better meets the needs of users with different time sensitivities.
