Today, IoT devices are ubiquitous and have pervaded almost every sphere of our lives, ushering an era of smart things:
- Smart homes have appliances, lights, and thermostat connected to the Internet .
- Smart medical appliances not only monitor remotely but also administer medicines timely .
- Smart bridges have sensors to monitor loads .
- Smart power grids detect disruptions and manage distribution of power .
- Smart machinery in industries have embedded sensors in heavy machinery to increase worker safety and improve automation .
To get a better understanding of the scale of IoT, here are some numbers for review:
- In 2008, the number of devices connected to the Internet surpassed the world population of approximately 6.7 billion people.
- In 2015, approximately 1.4 billion smartphones were shipped by manufacturers.
- By 2020, the prediction is that there will be 6.1 billion smartphone users and an anticipated 50 billion things connected to the Internet .
- By 2027, the expectation is that there will be 27 billion machine‐to‐machine connections in the industrial sector.
Now, if the focus shifts to the amount of data that gets generated, one gets a glimpse of the dawn of the zettabyte era . To put a zettabyte into perspective, 36,000 years of high‐definition television video would be the equivalent of one zettabyte. ...
