Nowadays we are connected through the internet via our smartphone,tablet,smart gadgets, Mini Drone and computer and all.
Then Question arises What would be the next era of Internet??
That would be Internet of things or internet of everything.
IoT describes a system where items in the physical world ,and sensors within or attached to those items are connected to the internet via wireless and wired Internet connections.These sensors can use various types of local area connection such as RFID, NFC ,Wi-Fi, Bluetooth.Sensors can also have connectivity such as GSM ,GPRS,3G and LTE.
IOT- “Internet of Things is a network of physical objects, systems platforms and applications that contain embedded technology to communicate and share intelligence with each other, the external environment and with people.“
IoT is already happening; here are some of the most enchanting ways that cities are utilizing big data and IoT to improve the quality of life.
1. Los Angeles is controlling traffic lights and reducing traffic congestion with this technology. The city is using traffic cameras and magnetic road sensors to control approximately 4,500 traffic signals in the city, reducing traffic cramming by up to 16 percent.
2. Porto, a city in Portugal, is testing a new way to create mobile Wi-Fi hotspots all over the city with the help of a tech startup called Veniam. The company has installed Wi-Fi transmitters in over 600 city buses and taxis, creating the largest Wi-Fi hotspot in the world. These routers provide free Wi-Fi to its citizens as a public utility. The data collected from this Internet usage can be used to offset the cost of the Wi-Fi in other areas. For instance, the sensors installed in the city helps waste management and saves man-hours by identifying which garbage cans actually need emptying.
3. New York is set to be the world’s first “quantified community”. All residents and environmental details will be tracked to help monitor pedestrian traffic flow. The city will also analyze how much solid waste is collected and what proportion of it is recyclable. This system will also collect data on residents’ health and activity levels through a mobile app.
4. “Smart water meters” are being used in the city of Long Beach, California to detect illegal watering in real time, aiding homeowners to cut their water usage by as much as 80 percent. This is a necessity for cities going through an acute drought, and at a time when the government is imposing tough restrictions on water usage.
5.Xcel Energy installed smart meters in customers’ homes to test “smart grids” in the city of Boulder, Colorado. This will allow users to look at their energy usage in real time simply by logging onto a website. This smart grid will help power companies to predict future usage and enable better planning for forthcoming infrastructure and energy requirements.
6. Songdo, a city in South Korea, has also taken a step towards improved trash collection. The city is partnering with Cisco to convert solid waste into fuel, by sorting, recycling, burying or burning the dumped waste. Cisco is also testing home appliances and utilities to enable them to be connected and controlled by a smartphone
These examples are just the beginning of the bright future ahead. With the integration of big data and IoT, our cities will become smarter, generate data that provides useful information and revolutionize our way of life.
