The Design And Implementation Of Ldap-Based IOT Node-Object Information Management System

The integration and interconnection of resources are the development trend of IoT. The Internet of Things (IoT) Node-Objects refer to the perceptual layer devices which are essential resources to be integrated in IoT environment. To achieve the goal of resource integration, we must formulate unified labels for IoT Node-Object, formulate unified storage and manage solution for the information of IoT Node-Objects. Directory is a mature solution for the problem on the interconnection of open systems and the integration of heterogeneous systems. This paper proposes an management of IoT Node-Object information,whose scheme based on LDAP and this management offers a unified solution to store and manage the information of IoT Node-Objects.Firstly, this paper proposes an unified identification standard for IoT Node-Objects reference to the structure of OID. On the next part, this paper proposes LDAP information models of Node-Object AtributeTypes and ObjectClasses, as well as designe the Directory Information Tree (DIT) of Node-Objects. Then, this paper constructs the service of collecting the information services of IoT Node-Objects management.Finally, this paper proposes a LDAP-based IoT Node-Object information management system based on the scheme proposed in this paper. Through applying this system in scenario "urban road environment management", this scheme is proved to be feasible and effective.
