Our open source IoT servers:
The technology industry and academia have entered a new cycle of technology innovation and growth, which we call Smart Computing.
After the mainframe computing, personal computing, and network computing Smart Computing has emerged.
Smart Computing provides low-cost, low power consumption and more human-like solutions to personal computing, multi-media and communication.
Smart Computing makes use of open source software more effectively. Computing devices have become smaller, more mobile, and smarter.
SmartComputerLab.org (SCLab) is a computer science laboratory aiming at the development of smart computer systems and applications
built on the newest technologies related to the ARM based SoCs and open source software.
Smart computer systems are high performance and low power consumption systems running under the control of the standard Linux OS.
They are built with the most recent SoCs like Samsung Exynos series 5xxx, RockChip series RK32xx, Nvidia Tegra K1,
Xilinx Zynq70xx, and many others. These SoCs integrate the data multiprocessing units and high-end graphic processors.
The use of standard packages and of the most advanced open source APIs and SDKs provide us with a complete set of tools
to develop almost an unlimited range of smart applications going from the wearable servers to the high performance computing
clusters including thousands of processing cores.
The wearable servers or IWAPs (Intelligent Wearable Access Point) run with less than 1W and provide the full Linux functionalities
allowing for the deployment of a large range of wireless services for close users.
On the other hand the clusters of credit size boards like Parallella or Tegra K1 SoCs offer the possibility of building smart super-computers.
Highly efficient multimedia systems may be developed rapidly on the base of the most recent SoCs like Exynos 5 Octa, Allwinner A80 or RK3288.
The smart boards are easily inter-connectable via Ethernet/WiFi and/or optic links including Ethernet switches and the smart routers based on
the same boards equipped with multiple network interfaces.
On the software side, the open source graphic, the computer vision, and the streaming APIs (openGL, openCV, Gstreamer,..)
provide us with multiple standard platforms for the development of multimedia systems.
High performance computing on smart systems may be easily provided via openMP, CUDA, openCL and openMPI software platforms.
Under their control hundreds or thousands processing cores may be united to provide the high operational performance required
for scientific and big-data processing.
OpenCL allows for the integration of heterogeneous processing units into one computing system including high-end ARM processors
with Mali-T600/T700, specific RISC processors (e.g. Epiphany) and Nvidia/AMD GPUs.
OpenCL also provides the interfaces for FPGA circuits (Altera/Xilinx) liberating the designer from
the painstaking coding with VHDL or Verilog HDL.
This site offers the presentations of subjects and projects developed in our laboratory.
The projects are based on different development boards with different ARM SoCs and open source software.
Training - teaching modules on mobile and autonomous platforms
The smart teaching platforms for practical classes cover a large spectrum of advanced digital technologies.
Attention: For the teaching modules we provide only the "synthetic" lectures that are the introductions and the guides to the best ,
video lectures from most renowned universities and companies.
They are built around the sets of most recent development boards, associated extensions and physical interfaces.
Each set contains a lapdock integrating the screen, the keyboard, the speakers, and the battery.
The lapdock may provide the power to the development board and has a 4 hour autonomy.
The whole platform for up to twelve teaching posts may be deployed in few minutes in any room equiped with simple tables and few electrical sockets.

A Smart Object is an object that enhances the interaction with not only people but also with other Smart Objects.
It can not only refer to interaction with physical world objects but also to interaction with virtual (smart computing environment) objects.
In our context a smart physical object has an embedded processor with physical interfaces to work with sensors and communication links (mainly radio links).
Smart Objects are the essential components of the Internet of Things .
In our laboratory we develop Smart Objects based on ESP8266 boards.
The ESP8266 is a micro-controller from Chinese manufacturer Espressif that includes Wi-Fi capability.
This small board allows the integrated micro-controller to connect to a Wi-Fi network in station and/or access point mode
and provides the complete stack of Internet Protocols allowing us to build client-server application with WEB server and many more.
ESP8266 uses the Cadence Tensilica LX106 micro-controller and the GCC toolchain.
It may be also programmed using Arduino IDE with a rich set of functionalities.
Since 2015 we have developed a number of projects based on Arduino (AVR) and ESP8266 boards.
With these projects we use many physical sensors and additional radio interfaces and
we created the networks with several ESP8266 communicating with different Internet protocols and
using different communication modes.
ESP8266 based boards as well as a number of Arduino (AVR) compatible boards are the base for practical classes of the IoT module.
In IoT module we are studying several connection and communication technologies including LoRa (Long Range WAN).
We have developed several simple LoRa terminals and gateways running on Arduino, ESP (Wemos D1), and Raspberry Pi 3.
These LoRa devices are extensively used in our exercises and projects providing complete IoT architectures.
