Applying SNMP Technology to Manage the Sensors in Internet of Things

Nowadays, the IoT is largely dependent on sensors. The IoT devices are embedded with sensors and have the ability to communicate. A variety of sensors play a key role in networked devices in IoT. In order to facilitate the man- agement of such sensors, this paper investigates how to use SNMP protocol, which is widely used in network device man- agement, to implement sensors information management of IoT system. The principles and implement details to setup the MIB file, agent and manager application are discussed. A prototype system is setup to validate our methods. The test re- sults show that because of its easy use and strong expansibility, SNMP is suitable and a bright way for sensors informa- tion management of IoT system. The Internet of Things (IoT) is the network of physical objects or things embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, op- erator and/or other connected devices. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure (1). The Internet of Things (IoT) transforms the everyday physical objects that surround us into an ecosystem of in- formation that will enrich our lives. The IoT is largely de- pendent on sensors. Sensors detect and measure changes in position, temperature, light, etc. and they are necessary to turn billions of objects into data-generating things that can report on their status, and in some cases, interact with their environment. For example, product and shelf sensors collect data throughout the entire supply chain. In the gaming indus- try, companies use tracking sensors to transfer the move- ments of users onto the screen and into the action. Internet- connected smart meters can measure power usage and pro- vide feedback to the power consumer, sometimes automati- cally adjusting the system's parameters. All of these facts show that sensors play a critical role in the IoT. So it's im- portant to ensure the normal operation of the sensors.
