Abstract
Simple Network Management Protocol (SNMP) is a well established protocol in network management. In order to apply this protocol in smart home environment, a proxy agent should be used. This proxy agent converts sensor readings to an SNMP compatible form. In this work LabVIEW toolkits are used to play this role. First by acquiring the sensors’ readings via multiple sub agents then sending them wirelessly to a single master agent through various approaches. The master agent completes the role of the proxy agent by storing these readings in a database file using LabVIEW database toolkits. This paper demonstrates a test bed representing this system is carried out and an SNMP software is used to monitor and control the sensors remotely. The results show that the proposed smart sending approach greatly reduced the amount of traffic needed.
Highlights
Smart is a word that is gaining rapid association with many usually dummy objects
As it is obvious in Figure 1; Simple Network Management Protocol (SNMP) aware devices could directly linked to an SNMP manger; while SNMP proxy agent should be used to link non SNMP devices
Once the management information base (MIB) is designed and compiled, the network-management systems (NMSs) can browse each sensor reading via the MIB browser tool of the WebNMS using the SNMP commands such as (Get, GetBulk, GetNetxt and Set), the master agent will respond to the SNMP command
Summary
Smart is a word that is gaining rapid association with many usually dummy objects These objects are very diverse in their sizes and applications ranging from small sized sensors and phones; towards cars and appliances; ending with buildings and cities. A smart device is a device that is capable of adapting to a variable environment in order to function in a predefined or adjustable manner This requires first, that these devices should sense the variations in the environment, sharing collected data with other devices or central coordinator to update a database that store history readings of such devices, take actions according to some sort of policy. WSN consists of a number of sensor nodes which can work together to monitor and manage the smart home to collect data about the environment in real-time [3]
