Scotland is to get a new Internet of Things network. The network, called IoT Scotland, will allow the collection of data from smart devices through a wireless sensor network based on LoRa wireless technology.
The £6m, three-year project has been funded with investment from both the public and private sectors.
Initially, the network will cover Scotland’s seven cities, Glasgow, Inverness, Edinburgh, Aberdeen, Dundee, Perth, and Stirling, with the aim of expanding it throughout Scotland.
Wi-Fi CERTIFIED EasyMesh™ brings a standards-based approach to Wi-Fi networks that utilize multiple access points (APs), combining the benefits of easy to use, self-adapting Wi-Fi with greater flexibility in device choice that comes with interoperable Wi-Fi CERTIFIED™ devices. Wi-Fi EasyMesh™ networks employ multiple access points that work together to form a unified network that provides smart, efficient Wi-Fi throughout the home and outdoor spaces.

From an article by Colm Gorey, Silicon Republic:
A peculiar trait of a cave-dwelling fish has inspired a device that could help us avoid disruption caused by a saturation of IoT signals in one place.
As we plough ahead towards a future where many city spaces are covered in connected devices as part of the internet of things (IoT), there are fears that we could reach the point of a spectral bandwidth crunch.
So, efforts to find ways for devices to avoid being jammed by a neighbouring signal have led researchers to some strange places, the latest of which happens to be home to a species of cave-dwelling fish.
In a paper published to the journal Optics Express, The Optical Society revealed how the species called Eigenmannia live in complete darkness.
In order to survive, they emit an electric field to communicate with other fish and to sense the surrounding environment. When two fish emit this field near each other, it has the potential to interfere with and jam the signal, which would obviously be bad for the fish.
However, thanks to a unique neural algorithm, the fish can adjust their electric communication signals to prevent this interference. For us humans, this same ability can be harnessed to create a light-based jamming avoidance response (JAR) device.
After a developer preview with more than 100,000 SDK downloads, Google has taken its Android Things managed IoT operating system out of beta and made it available to all developers.
Android Things is Google’s managed OS that enables users to build and maintain IoT devices at scale. It provides a robust platform that does the heavy lifting with certified hardware, developer APIs and secure managed software updates using Google’s back-end infrastructure.

Researchers have developed a new stretchable wearable sensor that can measure pH levels from a patient’s sweat—potentially replacing blood tests to measure glucose, sodium, and potassium.
The potential data that can be captured from sweat is equal to that of a blood test. The traditional check for chronic diseases is analyzing a blood sample. However, it is possible to use sweat and tears for the same tests as they contain similar analytes (biomarkers). A research team from the University Glasgow has developed a stretchable sensor that can measure sweat, using it to perform the same tests that would require blood.
The UK-based Bendable Electronics and Sensing Technologies (BEST) group works out of the University of Glasgow. It has developed a new sweat-based, non-invasive sensor directed at monitoring diabetes. The article, entitled “Stretchable wireless system for sweat pH monitoring,”was recently published in the journal Biosensors and Bioelectronics. This work was conducted by Wenting Dang, Libu Manjakkal, William Taube Navaraj, and Ravinder Dahiya from the University of Glasgow; Leandro Lorenzelli from the Fondazione Bruno Kessler; and Vincenzo Vinciguerra from STMicroelectronics. The sensor was developed via the EU-funded project CONTEST.
The wearable uses a pH sensor made from graphite-polyurethane composite, stretchable radio-frequency-identification (RFID) antenna, and a flexible data transmission printed circuit board (PCB). The sensor area is 1 cm2and can stretch up to 53% in length due to a pair of serpentine-shaped interconnecting pieces.

Arm has released a new processor core design for Cortex-M-powered system-on-chips that will try to stop physical tampering and side-channel attacks by hackers.
The microcontroller-grade Cortex M35-P CPU cores are aimed at embedded IoT devices that operate in public or areas where there is a risk someone will either crack open the device or get close enough to perform a proximity-based attack. Think things like smart meters or connected street lights in a major city.

“That’s right. Britain’s smart meters are now officially the most expensive smart meters in the world.” Full article by Nick Hunn can be found here:
For those of you who have not been following the story, let me provide a brief précis. Back in 2010 the Government mandated that every home in Britain should have a smart gas and a smart electricity meter by 2020. Instead of using off the shelf smart meters, they decided to design their own. DECC worked with some vested industry interests to do a classic Government IT committee job, producing the most complex smart meter specification the world has seen. That design was called SMETS1 – short for Smart Metering Equipment Technical Specification. Not only was it the most expensive, but it was also insecure. When GCHQ looked at it and considered the potential implications of connecting it to our national infrastructure they demanded a redesign, resulting in the SMETS2 specification. SMETS1 meters look as if they won’t work with the SMETS2 software infrastructure, so any SMETS1 meters already installed will probably need to be replaced. Throughout this fiasco, the Government has not relaxed its requirements for every home to have a smart meter fitted by 2020, which means fitting around 50 million new meters.
Which brings us to today. The SMETS2 meters are enormously complex and are pushing the limits of the industry to design them. With the 2020 deadline barely 30 months away you’d hope that the bulk of them would be fitted by now. But I’ve just been talking to contacts in the industry who have told me that currently there are only around 80 SMETS2 meters fitted. Do the sums based on what has been spent so far on the GB smart Metering programme and you’ll find that it equates to around £28 million for each of these meters. It is an obscene example of a Government IT project going wrong. But it gets worse. Not only will the overall project cost consumers around £12 billion, it has the potential to destroy Britain’s leading position in the development of the Internet of Things.
The Eclipse Internet of Things Working Group IoT Developer Survey 2018 collected feedback from 502 individuals between January and March 2018.
The key findings in this year’s edition of the survey include the following:
- Amazon AWS and Microsoft Azure are the top 2 cloud services for IoT. Google Cloud Platform is failing to get traction.
- MQTT remains the standard of choice for IoT messaging, while AMQP is becoming more and more popular as companies scale their IoT deployments and backend systems.
- 93% of the databases and data stores used for IoT are open source software. Data collected and used in IoT applications is incredibly diverse, from time series sensor data to device information to logs.

National Institute of Standards and Technology (NIST) have published a report on Lightweight Cryptography.
NIST approved cryptographic standards were designed to perform well on general purpose computers. In recent years,there has been increased deployment of small computing devices that have limited resources with which to implement cryptography. When current
NIST approved algorithms can be engineered to fit into the limited resources of constrained environments, their performance may not be acceptable. For these reasons, NIST started a lightweight cryptography project that was tasked with learning more about the issues and developing a strategy for the standardization of lightweight cryptographic algorithms. This report provides an overview of the lightweight cryptography project at NIST, and describes plans for the standardization of
lightweight cryptographic algorithms.
