摘　　要：为了管理信息中心物联网(IC-IoT)不断变化的网络状态信息,本文针对IC-IoT提出一种节点状态监测方案,以更好适应未来网络的发展。首先提出一种新的管理信息库结构用于记录各种网络节点状态信息,采用信息中心网络(ICN)的命名格式,以网络节点状态内容本身为中心。在此架构上采用跟踪路由方法,结合基于数据块重要性的自适应数据放置策略来获得所需的网络状态信息,提高网络节点状态信息检索效率,同时设计了安全防护机制来达到保证数据机密性与对管理用户进行访问控制的目的。搭建网络仿真测试环境评估了上述跟踪路由机制、自适应数据放置策略、访问控制安全防护带来的时延影响,仿真结果表明此方案能够有效地提高数据获取效率,访问控制模型提供了数据机密性和其他安全性功能,仅附加了少量的计算成本。To manage the constantly changing network status information of the information-centric Internet of Things(IC-IoT),this study proposes a node status monitoring program for the IC-IoT.It first proposes a new management information base structure for recording various network node status information,and adopts the naming format of information-centric networking(ICN),centering on the content of the network node status.In this architecture,we combine the trace route method and adaptive data placement strategy according to the importance of the data block,to obtain the required network status information and improve the retrieval efficiency.At the same time,this scheme designs a security protection mechanism to achieve the purpose of ensuring data confidentiality and access control for management users.Finally,through the establishment of a network simulation test environment,time delay brought by the above-mentioned trace routing mechanism,adaptive data placement strategy,and access control security protection is evaluated.The simulation results show that this scheme can effectively improve the efficiency of data acquisition.The access control model provides data confidentiality and other security functions for the solution,while only brings a small amount of computational cost.
