Distributed storage system model design in internet of things based on hash distribution

摘要

Through analysing the characteristics of the data processing in internet of things (IoT), the author puts forward the distributed storage system model based on hash distribution. On the basis of massive amounts of data distribution in the IoT, this model completed the data backup protocol based on master copy of distributed design and the Paxos distributed system protocol on the basis of the principle of consistency distribution of hash algorithm which fully considers load balancing. At the same time, the authors make simulation of the process of data storage through OPNET Modeller simulation software, and then we completed performance evaluation for the designed storage model through OPNET Modeller. The simulation results show that the distributed storage system model design increases by 12.2% in terms of throughput, and the response latency decreases by 9.8% compared with sequential storage distribution policy. In addition, the random writing speed is about 8 Mb/s.
