IDG Contributor Network: Monitoring the Amazon wildfires with satellites, IoT sensors and GIS

The Amazon spans 2.1 million square miles of rain forest spread over nine countries. And on its edges are miles of agricultural fields, whose farmers routinely burn in order to control pests and weeds, and to encourage new growth.Brazil is the largest cattle exporter in the world with over 200 million head of cattle. Ranchers often set fires to clear land for grazing, reports the Yale School of Forestry and Environmental Studies. However, these long-practiced techniques have raised concerns of the threat that accidental forest fires could pose during drought years. Climate change, which is beginning to show its effects around the world, could exacerbate this threat.To read this article in full, please click here

IDG Contributor Network: IoT-enabled shipping containers sail the high seas improving global supply chains.

Global trade flows through shipping containers. Manufacturers depend on them to get raw materials in time and to ship finished products to market. IoT is being applied to monitor containers and make sure that their contents aren’t damaged or stolen.Inter-modal containers Containers have standardized dimensions, which lets transporters easily ship, stack and store them. There are over twenty million containers in motion right now. Containers are pre-filled which reduces the time that trucks need to get loaded. Their standard size allows them to be easily transferred between trucks, planes, ships and trains.Global supply chains based on containers enable manufacturers to minimize their costs with ‘just-in-time’ inventory. This makes it important to track containers’ location and the condition of their contents.To read this article in full, please click here

IDG Contributor Network: Robots extend the scope of IoT applications

Robots and IoT devices are similar in that they both rely on sensors to understand their environment, rapidly process large streams of data and decide how to respond.That’s where the similarities end. Most IoT applications handle well-defined tasks, whereas robots autonomously handle anticipated situations. Let’s consider both from six different vectors:1. Sensor IoT – Binary output from stationary sensor. “Is the door open or closed?” Robots – Complex output from multiple sensors. “What is in front of me? How do I navigate around it?” 2. Processing IoT – Simple data stream of signals handled with well-known programming methods. Robots – Large complex data streams handled by neural network computing. 3. Mobility IoT – Sensors are stationary and signal processing is done in the cloud. Robots – The sensor laden robot is mobile and signal processing is done locally and autonomously. 4. Response IoT – The action to take in response to a situation is well defined. Robots – Multiple actions could be taken in response to a situation. 5. Learning IoT – The application typically does not ‘evolve’ on its own and develop new features. Robots – Machine learning and other techniques are used to let Continue reading

IDG Contributor Network: Did IoT cyberattacks cause NY power transformers to explode?

Officials blamed a power surge for the blackout on Dec. 28th that left LaGuardia airport in the dark for about 45 minutes, grounding flights. A look at the trend of power outages at American airports shows a disturbing pattern and possibly sinister cause.Background Attacking an adversary’s infrastructure is asymmetrical warfare. It causes a lot of damage for a very small cost. Cyberattacks are an ideal weapon as they disguise who might be behind them, making retaliation much harder.

IDG Contributor Network: Improving supply chains with the IoT and blockchain

The U.S. Centers for Disease Control and Prevention recently advised "consumers to throw away any store-bought romaine lettuce and warned restaurants not to serve it amid an E. coli outbreak that has sickened more than 50 people in several states."This problem highlights the dangers of modern supply chains. They help lower costs and improve business efficiency, but they’re complex and a single failure can sicken people thousands of miles away. The food we eat and the medicines we use come from remote suppliers, transported in refrigerated trucks, and stored in different warehouses. How can perishable commodities be tracked from suppliers to customers? How can the temperature conditions during shipment be monitored to avoid contamination? How can spoilt products be quickly recalled even if they’re in transit or stored in a warehouse?To read this article in full, please click here

IDG Contributor Network: How IoT trackers can fight poachers

Sea turtles have been survived for millions of years, but now face extinction. as poachers. How do you protect sea turtles eggs on remote, miles-long beaches in developing countries from poachers working in the dark?Global System for Mobile Communications, or GSM, enabled IoT trackers may provide an answer to this scourge.Background Poachers kill sea turtles for their shells and their eggs are considered a delicacy and aphrodisiac. Sad but true. The trade of sea turtle products is restricted, but that doesn’t stop poachers. Tracking this illegal trafficking is difficult. The transit routes and final destinations are unknown.Sea turtle products are the second most frequently trafficked wildlife product smuggled from Latin America to the US. Eggs are a quarter of illegal imports and most originate in Mexico or Central America. This trade is devastating to turtle populations. A recent shipment of a thousand turtle eggs that was intercepted at the Mexico/U.S. border represented nearly 5 percent of the year’s total egg production for the beach from which they were poached!To read this article in full, please click here

IDG Contributor Network: IoT devices communicate by Chirping

Most IoT systems assume there will be some form of connectivity. But what happens when there isn’t any Bluetooth, WiFi or cellular connectivity? R2D2, the adorable robot from Star Wars, may have the answer with the bird-like noises he used to communicate.How can sensors share data when connectivity isn’t available? How can IoT devices be designed to last longer without being recharged? How can legacy equipment be retrofitted affordable to communicate with other devices?Most IoT devices communicate through either a Bluetooth, WiFi, LoRaWAN, SIGfox or cellular connection. The mode chosen is determined by the size of the payload to be transmitted, distance to be traversed, and the power available to the transmitting device. Walls, other electronic equipment and conflicting radio signals also influences the selection of the protocol to be used. What’s needed is that can work in ‘noisy’ environments and work with very little power.To read this article in full, please click here
