LL5 - Internet of things


Internet of Things is a new concept that defines a scenario where everyday physical objects will be connected to the Internet, will interoperation with other objects and systems; and will be able to identify themselves to other devices. This will increase dramatically the number of connect items to the networks that could be transformative of daily life. This living lab will focus in different scenarios that will be addressed in a short future and where the focus of this project will help to develop new functionalities.

This Living Lab includes five use cases that will allow showing implementations like audio and video communications over WebRTC (using the web browser as the device), open deterministic networks, automatic home networking, ultralowpower high database communication, and synchronized low-latency deterministic networks.

This first use case will address large-scale application of Unified Communication Services using HTML5 based Web Browsers on Embedded Systems. The main goal is to implement WebRTC in any type of small embedded systems, to have the possibility to adapt these systems to the new paradigm (where the web browser is going to be the player). An additional target is to showcase the capability of the WebRTC technology and paradigm to be integrated with digital and analog radio communication systems in safety critical communication applications in the domains public transport, public safety and air traffic management.

By open deterministic networks we will try to demonstrate that the developments conducted have been taken to the next level in cross domain industrial applications. The aim is to showcase the potential of open deterministic networking by connecting a variety of local embedded systems to other embedded systems in the area of transportation industrial domains. Such an open deterministic network together with mixed-safety-criticality applications and security-domain-separated applications utilizing multi-core technology potentially enable public transport and public safety organizations to utilize the same network infrastructure and network devices where today multiple infrastructures are used. The goal is to implement a demonstration for these scenarios and to elaborate safety and trust cases accordingly.

This use case shall achieve a cross-domain industrial demonstrator, show-casing the capabilities of enhanced functionality and performance of open deterministic networks based on the TTEthernet Platform.

The results shall allow to draw significant conclusions for the different industrial domains in order to drive forward developments in the following directions:

  • Autonomous driving (safety- and security- aspects combined with wireless performance (i.e. Car2X communication interface for TTEthernet required))
  • Video surveillance (acquisition, transfer, storage of heterogeneous data in a wireless network of intelligent cameras)
  • Performance issues in deterministic networks finally being also targeted for police and fire department as well as railway communication networks with high participant counts, and mixed criticality communication applications on top of the network
  • Investigate building of trust cases taking into account safety as well as security requirements and life-time maintenance issues
  • Investigate deterministic, service oriented networks using Multiple Processor Systems on a Chip (MPSoC) architectures
  • Investigate effects on certifiability for aerospace and automotive industrial domains

The spectacular increase of interconnected devices, services, networks and even people over the future internet leads to a managerial havoc of unprecedented magnitude. Novel technologies encompass enormous numbers of communicating and interacting entities. These entities should harmoniously cooperate with each other, in order to be effective. As the numbers of these interacting entities increase, ensuring their efficient cooperation becomes increasingly complex. High complexity renders the quest for innovative approaches a basic prerequisite, for the consolidation of numerous innovations in the wireless world. A valid solution to tackle complexity is to infuse self-x (self-management, self-configuration, self-healing, etc) properties to the entities, so as to allow them to operate and organize autonomously, introducing what is called: "autonomic systems".

In this respect, the objective of this Use case is to design, develop and implement all technologies that are relevant to management of home networks in accordance with the autonomic computing paradigm.

The figure above illustrates the various technologies available for home networking and how these can coexist in the domestic environment. Multimode fibers can be used to distribute data inside the building in the Fiber-to-the-Building (FTTB) access scenario or from room-to-room in the FTTH scenario. If it is preferable not to install new wires, then the home network backbone can instead rely on PLC at the cost of reduced data rate and reach. In the wireless front, several technologies can be used for networking including WiFi, 60GHz and THz wireless and optical wireless (both visible light communications – VLC and infrared). Each wireless and wireline technology comes with its own merits and pitfalls, promoting the use of hybrid solution and the need for interconnecting all these heterogeneous technologies.

The use case “ultralowpower high database communication” wants to realize a multiprocessor platform, tuned to our target applications, which achieves a power consumption which is a factor lower than the present state of the art. This will be done by the realization of a 802.11n/ah medium data rate, ultra low power solution, where the lower power can mean a breakthrough in terms of overall system power and cost.

Compared to the present state of the Art the EMC² goals are:

  • Realize a multiprocessor platform, tuned to our target applications, which achieves a power consumption which is a factor [3 or better] lower than the present state of the art. Our starting point today – the BLUSP – in our analysis is achieving a factor 3 better in power consumption compared to present comparable architectures.
  • Realize a programming model which is close to standard C programming model for its users.
  • Demonstrate this by one of the target applications, where the lower power can mean a breakthrough in terms of over system power and cost.

This use case pretends to demonstrate the benefits and possible applications of using low latency networks with high accuracy time synchronization. The target goal is to provide synchronization capabilities of distributed multicore systems with an accuracy of few hundred of picoseconds but based on widely known standards as IEEE-1588v2 with the proper protocol extensions. Additionally, the network elements should be capable of handle Ethernet traffic with very low latency and with high determinism. The inclusion of extended QoS features integrated with the previous properties shall allow the development of mixed-criticality applications for many different industrial domains. As example of target applications, we could consider highly scalable Smart-grid systems, industrial automation over wide areas, high accuracy positioning systems, high accurate Internet quality of service measurement or distributed modular airborne development between others.

The use case will produce a demonstrator that illustrates the benefits and capabilities of the presented approach on different industrial domain with focus on Smart Grids.
