The International Conference on Embedded Wireless Systems and Networks (EWSN) is a highly selective single-track international conference focussing on premier research results at the intersection of embedded systems and wireless networking – an area of highest relevance for visionary technologies such as the Internet of Things or Cyber-Physical Systems and application domains such as Smart Production, Smart Cities, or Connected Cars.
The featured topic of the 2016 edition of EWSN is “Dependability” and we specifically welcome contributions that aim at making networked embedded systems more reliable, predictable, safe, and secure in order to enable critical applications that require guaranteed performance.
EWSN has been established in 2004 as the European Conference on Wireless Sensor Networks and has been held since then in European cities. For the 2016 edition, the scope still includes Wireless Sensor Networks, but has been broadened to all topics at the intersection of embedded systems and wireless networks.

The Weightless SIG today announced the deployment of a Weightless-N Smart City network in the heart of the UK’s capital. The network, operating on Nwave technology, has been deployed in conjunction with the Digital Catapult national centre to rapidly advance the UK’s best digital ideas, which is making available the infrastructure on which Weightless base stations are deployed.
Operating in sub-1GHz, licence-exempt ISM spectrum using ultra narrow band (UNB) technology, Weightless-N offers best-in-class signal propagation characteristics, leading to excellent range of several kilometres, even in challenging urban environments such as the city of London. Very low power consumption provides end points with exceptionally long battery life measured in years from small conventional cells, and leading edge innovation in design minimises both terminal hardware and network costs.
London is one of the world’s largest cities, the largest municipality in Europe with over 21 million people in a metropolitan area covering over 8000 square kilometres. Siting of base stations to support an efficient, low cost city-wide network is an important part of the deployment planning process.
“We are delighted to be able to provide a platform to showcase Weightless-N technology, a key enabler for Smart City projects not just across the capital but around the world,” said Peter Karney, Head of Engineering, Digital Catapult. “We are looking forward to opening this up to our network to enable them to continue to showcase the UK’s innovation in this area; we will be leading an open call in the near future allowing these innovators to register their interest in the project.”
Network modeling predicts coverage encompassing well known London landmarks including Buckingham Palace, the Houses of Parliament and the Tower of London to the south and the Emirates Stadium to the north. Independent real world signal verification will shortly be carried out to provide an accurate coverage map and this will be published on the Weightless website when complete.
Yury Birchenko, CEO of Nwave Technologies, described the network as “a groundbreaking milestone – the first public network deployment from Nwave since the publication of the Weightless-N open standard”.
Weightless-N is designed around a differential binary phase shift keying (DBPSK) digital modulation scheme to transmit within narrow frequency bands using a frequency hopping algorithm for interference mitigation and enhanced security. It provides for encryption and implicit authentication using a shared secret key regime to encode transmitted information via a 128 bit AES algorithm. The technology supports mobility with the network automatically routing terminal messages to the correct destination. Multiple networks, typically operated by different companies, are enabled and can be co-located. Each base station queries a central database to determine which network the terminal is registered to in order to decode and route data accordingly.

The Weightless SIG announced the publication of version 1.0 of the new Weightless-N open standard based on a low power wide area star network architecture. Operating in sub-GHz spectrum using ultra narrow band (UNB) technology, Weightless-N offers best in class signal propagation characteristics leading to excellent range of several kilometres even in challenging urban environments. Very low power consumption provides for exceptionally long battery life measured in years from small conventional cells and leading edge innovation in design minimises both terminal hardware and network costs.
Central to the Weightless proposition is its status as an open standard. Weightless is differentiated from all alternative proprietary LPWAN technologies by uniquely enabling a competitive, free and fair market that does not lock developers into using particular vendors or network service providers.
Details of hardware supporting Weightless-N as well as SDKs will be made available on the Weightless website shortly.

Cyber-physical systems (CPS) are complex engineering systems that rely on the integration of physical, computation, and communication processes to function. Theories, algorithms, systems and methodologies developed for CPS are the foundations for applications like Internet of Things, industrial internet and automation, smart transportations, smart grids, smart cities, buildings and homes, data centers, health care, wellbeing and so on. Such systems must be operated safely, dependably, securely, efficiently and in real-time. Advances in this field will have great technical, economic and societal impacts in the near future. Since 2008, CPS Week is the premier forum for academic, industry, and governmental researchers to present latest research results and exchange ideas on all aspects of CPS.
CPS Week 2015 will be held in the beautiful city of Seattle, Washington, USA.
The event features four major collocated conferences:
In additional to major conferences, CPS Week 2015 will host workshops, tutorials, poster and demo sessions, competition, and PhD forums.
Abstract Registration: October 13th, 2014
Submission Deadline: October 20th, 2014
Notification Dates: vary by individual conferences
Workshop Date: April 13th, 2015
Main Conference: April 14th – April 16th, 2015

WiFi infrastructure is everywhere which makes easier to make network of devices connected to WiFi.
There is also great range of WIFI routers with different space coverage and speeds, and as they are mass produced product the prices are at the rock bottom if we have to compare to Zigbee or Bluetooth.
WiFi stack require resources though and not quite good for smallish 8bit populary hobby processors, this is why UART-to-WIFI solutions were made and become popular.
Texas Instruments released CC3000 which cost about $20-25 in single quantities and $10 in volume.
It took no longer and Chinese company Espressif released their ESP8266 highly integrated UART-WIFI bridge IC, it requires just quartz crystal and balun to make WIFI module, their reference design is with just 11 x 12 mm board space!
And of course this comes at Chinese prices: you can buy ESP8266 module in single quantity from Seedstudio for $6.95 or from Alibaba for $5!
On top of this you can easy connect devices to Internet and send and receive data through UART!
This will definitely wipe out the $50-60 Arduino WIFI shields and even Microchip’s MRF24WB0MA etc modules.
We are going definitely to release MOD-ESP8266 which to connect to all our boards with UEXT and give possibility to connect to Internet with simple AT commands!
With MOD-IO2+MOD-ESP8266 for instance anyone could make WIFI enabled relay and Inputs and monitor through web page the inputs and drive relays for extremly low cost!
