A novel method of IoT wireless sensor nodes management based on OID technology

Abstract

Abstract With the continuous development of Internet of Things (IoT) technologies, massive wireless sensor nodes are deployed to construct several local wireless sensor networks over the world, which bring a great challenge to enormous wireless sensor nodes management. In this paper, a mechanism of sensor node managed object identifier (OID) is designed to merge classic SNMP MIB managed object identifier with sensor node identifier. Then, the framework of classic SNMP manager and agent is modified and optimised. Finally, a method for sensor nodes remote managing, which adapts to heterogeneous IoT network such as Internet linked with industry wireless network etc., is proposed to achieve hierarchical addressing and unified management of massive sensor nodes. The experimental result demonstrates that the proposed method satisfies the unified managing demand of a tremendous amount of sensor nodes in large-scale IoT network scenario by configuring and controlling sensor nodes.
