摘　　要：针对基于DNS技术的EPCglobal ONS系统存在负载不均衡,查询时延较大等缺点,提出基于改进DHT机制的层次化ONS解析系统,运用OverSim网络仿真平台进行仿真实验。实验结果表明基于DHT机制的ONS解析系统能够有效地应对单点失效,平均查询时延波动轻微,相比于EPCglobal ONS系统具有更好的负载均衡性能,这个特性极其适合地址空间急剧增长的物联网,对加快物联网的发展具有很重要的现实意义。The DNS-based ONS system has the load imbalance shortcoming and the low efficiency in the EPCglobal network, so this paper proposes a new improved DHT-based and hierarchical ONS resolution mechanism. Simulation experiments by OverSim network simulation platform, it proves that DHT-based ONS resolution system can effectively respond to a failure of single point. The average query delay fluctuates slightly. The system has better load balancing performance compared to DNS-based ONS system. This feature of better load balance is extremely suitable for the rapid growth in the address space, and has highly practical importance to the rapid development of the Internet of Things.
