Dynamic and Self Adapting

 

IoT Characteristics with Examples - Dynamic and Self Adapting Icon

 

In IoT, the sensors or devices respond to dynamic events and have the ability to adapt to the change in the environment. Consider a surveillance system where cameras are installed for monitoring a location. Whenever there are no objects in front of the camera, the camera will be in a low power mode.

 

Surveillance System IoT

 

Whenever an object is detected, the camera resumes its activity of monitoring that object. This is the dynamic behaviour. The cameras also respond to changes in the environment. If it is night time, the cameras might shift to infrared mode and vice versa during day time. Also, the cameras can adjust their picture clarity based on the environment. Thus IoT devices can self adapt to changes in the environment.

 

Self Configuring

 

Self Configuring IoT

 

The IoT sensors or devices have the capability to obtain the instructions from a remote location for installing, updating or other management related tasks. In a weather monitoring system, several sensor nodes or devices will be placed at different locations in a vast area. These nodes might be powered using natural energy sources.

 

Weather Monitoring IoT

 

These nodes from time to time receive updates or instructions from a remote management server to update the firmware, or remote start up and shut down. This self configuration ability of the nodes reduces the human intervention to visit and update all the nodes manually.

 

Interoperable Communication Protocols

 

Interoperable Communication Protocols IoT

 

Since the emergence of IoT, different communities developed different proprietary protocols which may not be interoperable across different devices. These protocols are being standardized so that they can be used across different devices. Some of the interoperable or standardized protocols are TCP, UDP, IEEE 802.15.4, 6LoWPAN, etc.

 

Unique Identity

 

Unique Identity IoT

 

All the devices in IoT will be having unique identities so that it will be easy to identify the device for management purpose. Some of the ways for providing unique identities are by using IP address, Uniform Resource Identifiers (URIs), and RFID tags.

 

Integration into Information Network

 

Integration into Information Network IoT

 

All the sensors or different devices in IoT are connected to Internet or other communication pathway. The data from sensors is aggregated and pre-processed at the local site or in the cloud. Information can be extracted from the data and appropriate decision can be made.

 

Forest Fire Monitoring System IoT

 

As an example, consider fire monitoring system in which different sensors are spread across the trees in a forest. These sensors send the data to a local sink node which is connected to the Internet. This data is analyzed and alerts are generated which are taken care by the appropriate personnel.
