Ultra Reliable Communication via Network Coded Cooperation NCC

Whether Industry 4.0, smart flow of goods or networked mobility: Digitization requires a lot of communication in networked systems, especially wirelessly networked, embedded, electronic systems - wherever mobility, flexibility or retrofitting in an existing environment are requirements.

At the application level, the requirements for the level of detail in digitization and for data quality continue to grow. Data-driven approaches such as learning systems or AI are also dependent on huge amounts of data. As a result, more and more data is generated that, in wireless systems, has to be transmitted over a shared radio resource.

Network Coded Cooperation, as a network-based coding method, has the potential to reduce the need for communication in the wireless network and, at the same time  increase robustness. There is also the possibility that the individual radio node manages with a lower transmission power or that antenna diversity can be dispensed with, because this can be compensated for through the cooperation.

The advantages of network coding are:

  • Increasing data throughput by combining data packets on the way to the receiver
  • Increasing robustness against transmission errors by using redundant data and spatial diversity of different transmission paths
  • Increasing efficiency and reduction of network traffic by flexibly combining data packets instead of serial transmission
  • Increasing network flexibility and better routing by using spatial diversity of different transmission paths, cooperation and flexible combination of data packets

Use of Network Coded Cooperation

Network Coded Cooperation is already used at Fraunhofer IIS for some technologies:

IO-Link Wireless

Industrial wireless networking with deterministic cycle time 

The IO-Link wireless radio technology, which can be used worldwide, provides a cost-effective, highly reliable and deterministic communication standard. This technology is an extension of IO-Link on the physical level and defines wireless communication between sensors and actuators to the PLC in the environment of Industry 4.0.

UWIN – Ultra reliable Wireless Industrial Network

Wireless real-time communication with maximum reliability

In industrial automation systems, some of the sensors and actuators as well as other automation components are typically located on moving subsystems. Tools on robot arms, slide tracks as well as rotary and coordinate tables are examples of such sub-systems, for whose control a connection with very short cycle times in the single-digit millisecond range to the higher-level control is necessary. The cable drag chains, rotary feedthroughs and sliding contacts used today for this purpose have numerous disadvantages, such as susceptibility to wear, high weight, limited expandability or restrictions on mobility.

To solve this problem, Fraunhofer IIS is developing the radio technology "Ultra reliable Wireless Industrial Network" (UWIN), which can be used as a wireless extension or as a replacement for wired field buses. Compared to today's wireless technologies, this enables real-time signal transmission with extremely short latency times and maximum reliability.
