IoT – Internet of things, is the science of an interconnected everyday life through devices communicating over WiFi, cellular, ZigBee, Bluetooth, and other wireless, wired protocols, RFID (radio frequency identification), sensors and smartphones. Data monetization has lead to generating revenue by gathering, analyzing customer data, industrial data, web logs from traditional IT systems, online stream, mobile devices and sensors and an interconnection of them all, in other words, IoT. IoT is hailed as the new way to transform the education sector, retail, customer care, logistics, supply chain and health care. IoT and data monetization have a domino effect on each other which generate actionable insights for business metrics, transformation and further innovation.
The wearable devices are a great way to keep tab on patient heart rates, step counts, calories consumed and burnt. The data gathered from such devices are not only beneficial for checking vital signs but also can be used to scrutinize effectiveness of drug trials, analyzing the causes behind the way body reacts to different stimulus. IoT in logistics, by reading the bar codes at every touch point that track the delivery of products, comparing the estimated with the actual time of delivery, analyzing the reasons causing the difference can help businesses bolster better processes. In Smart buildings, HVAC (heating, ventilation, air conditioning), electric meters, security alarm data are integrated, analyzed to monitor building security, improve operational efficiencies, reducing energy consumption and improving occupant experiences.
IoT is expected to generate large amounts of data from varied sources with a high volume and very high-velocity, thereby increasing the need to better index, store and process such data. Earlier the data gathered from each of the sources was analyzed in a central hub and communicated to other devices, but the IoT brings a new dimension called the M2M (machine to machine) communication. The highlights of such M2M platforms are
- Improved device connectivity
- API, JSON, RDF/XML integration availability for data exchange
- Flexible to be able to capture all formats of data
- Data Scalability
- Data security across multiple protocols
- Real-time data management – On premise, cloud or hybrid platforms
- Low TCO (total cost of ownership)
The data flow for an end-to-end IoT usecase entails capturing sensor-based data using SPARQL for RDF encoded data from different devices, wearables into a common data platform to be standardised, processed, analyzed and communicated further as dashboards, insights, as input to some other device or for continuous business growth and transformation. Splunk, Amazon, Axeda are some of the M2M platform vendors that provide end to end connectivity of multiple devices, data security and realtime data storage and mining advantages. Data security is another important aspect of IoT, adhering to data retention policies. As IoT evolves, so will the interconnectivity of machine-to-machine platforms, exciting times ahead!
