The importance of network architecture on the Internet of Things
There are a lot of moving parts in the networking for the Internet of Things; a lot to sort out between WiFi, WiFi LP, Bluetooth, Bluetooth LE, Zigbee, Z-Wave, EnOcean and others. Some standards are governed by open, independent standards bodies, while others are developed by a single company and are being positioned as defacto standards. Some are well established, others are in the early adoption stage. All were initially developed to meet unique application-specific requirements such as range, power consumption, bandwidth, and scalability. Although these are familiar issues, they take on a new urgency in IoT networks.
To begin establishing the right networking technology for your application, it is important to first understand the network architecture, or the network topology, that is supported by each technology standard. The networking standards being used today in IoT can be categorized into three basic network topologies; point-to-point, star, and mesh.
The following figure illustrates these three topologies followed by a deeper discussion of each.
Network technologies appropriate for Internet of Things
An application developer has to consider numerous networking attributes when choosing a wireless network. The following five can help you understand the characteristics, capabilities, and behavior of the three topologies.
Is freedom just another word for a smart environment?
You know the “Next Big Thing” is no longer waiting in the wings when you hear it dissected on talk radio. That’s now the case with the Industrial Internet — or the Internet of Things, or the collision of software and hardware, or the convergence of the virtual and real worlds, or whatever you want to call it. It has emerged from academe and the high tech redoubts of Silicon Valley, and invaded the mainstream media.
Of course, it’s been “here” for a while, in the form of intelligent devices, such as the Nest Thermostat, and initiatives like the Open Auto Alliance, an effort involving Audi, GM, Honda , Hyundai, Google and Nvidia to develop an open-source, Android-based software platform for cars.
But we are now tap-dancing one of those darn tipping points again. As software-enhanced objects, cheap sensors, and wireless technology combine to connect everything and everybody with every other thing and person, a general awareness is dawning. People — all people, not just the technologically proficient — understand their lives are about to change big time. This is creating some hand-wringing anxiety as well as giddy anticipation, and rightly so: the parameters and consequences of the Internet of Things remain vague. Read more…
A multitude of signals points to the convergence of software and the physical world.
Our new Solid conference is about the “intersection of software and hardware.” But what does the intersection of software and hardware mean? We’re putting on a conference because we see something distinctly new happening.
Roughly a year ago, we sat around a table in Sebastopol to survey some interesting trends in technology. There were many: robotics, sensor networks, the Internet of Things, the Industrial Internet, the professionalization of the Maker movement, hardware-oriented startups. It was a confusing picture, until we realized that these weren’t separate trends. They’re all more alike than different—they are all the visible result of the same underlying forces. Startups like FitBit and Withings were taking familiar old devices, like pedometers and bathroom scales, and making them intelligent by adding computer power and network connections. At the other end of the industrial scale, GE was doing the same thing to jet engines and locomotives. Our homes are increasingly the domain of smart robots, including Roombas and 3D printers, and we’ve started looking forward to self-driving cars and personal autonomous drones. Every interesting new product has a network connection—be it WiFi, Bluetooth, Zigbee, or even a basic form of piggybacking through a USB connection to a PC. Everything has a sensor, and devices as dissimilar as an iPhone and a Kinect are stuffed with them. We spent 30 or more years moving from atoms to bits; now it feels like we’re pushing the bits back into the atoms. And we realized that the intersection of these trends—the conjunction of hardware, software, networking, data, and intelligence—was the real “news,” far more important than any individual trend.
The Jawbone UP shows the promise available in all kinds of wearable sensors.
In a recent conversation, I described my phone as “everything that Compaq marketing promised the iPAQ was going to be.” It was the first device I really carried around and used as an extension of my normal computing activities. Of course, everything I did on the iPAQ can be done much more easily on a smartphone these days, so my iPAQ sits in a closet, hoping that one day I might notice and run Linux on it.
In the decade and a half since the iPAQ hit the market, battery capacity has improved and power consumption has gone down for many types of computing devices. In the Wi-Fi arena, we’ve turned phones into sensors to track motion throughout public spaces, and, in essence, “outsourced” the sensor to individual customers.
Phones, however, are relatively large devices, and the I/O capabilities of the phone aren’t needed in most sensor operations. A smartphone today can measure motion and acceleration, and even position through GPS. However, in many cases, display isn’t needed on the sensor itself, and the data to be collected might need another type of sensor. Many inexpensive sensors are available today to measure temperature, humidity, or even air quality. By moving the I/O from the sensor itself onto a centralized device, the battery power can be devoted almost entirely to collecting data.
A conversation with Chris Anderson, Nick Pinkston, and Jie Qi
Manufacturing is hard, but it’s getting easier. In every stage of the manufacturing process–prototyping, small runs, large runs, marketing, fulfillment–cheap tools and service models have become available, dramatically decreasing the amount of capital required to start building something and the expense of revising and improving a product once it’s in production.
In this episode of the Radar podcast, we speak with Chris Anderson, CEO and co-founder of 3D Robotics; Nick Pinkston, a manufacturing expert who’s working to make building things easy for anyone; and Jie Qi, a student at the MIT Media Lab whose recent research has focused on the factories of Shenzhen.
Along the way we talk about the differences between Tesla’s auto plant and its previous incarnation as the NUMMI plant; the differences between on-shoring, re-shoring and near-shoring; and how the innovative energy of Kickstarter and the Maker movement can be brought to underprivileged populations.
Many of these topics will come up at Solid, O’Reilly’s new conference about the intersection of software and the physical world. Solid’s call for proposals open through December 9. We’re planning a series of Solid meet-ups, plant tours, and books about the collision of real and virtual; if you’ve got an idea for something the series should explore, please reach out!
