"Cutting-edge research requires excellent minds – particularly more females – at all levels. Launch your mission with us and send in your application now!" Prof. Pascale Ehrenfreund - Chair of the DLR Executive Board

The Information Transmission Group of the Satellite Networks Department focuses on the design and the analysis of information transmission systems, with emphasis on the modulation, error control coding, signal processing and medium access control aspects. The goal is to lead the evolution of satellite and space communications air interfaces towards higher throughput and reliability relying on solid theoretical foundations.

Blockchain is emerging as a key solution to enable safe and decentralized interactions within a broad range of systems, and has nowadays found applications that go beyond the original cryptocurrency implementation. In particular, the technology has recently drawn interest in the domain of machine type communications and the internet of things (IoT), where it has the potential of enabling secure and resilient exchange of information in large, non-centralized network of devices such as, for instance, smart grids or industry 4.0 setups.

Problem description While appealing, the application of blockchain to the internet of things poses specific and non-trivial challenges. On the one hand, IoT devices are often low-power and low-complexity, preventing the implementation of complex protocol stacks, and rendering transmission and reception of messages costly in terms of available resources. Moreover, machine- type communications typically involve exchange of data packets among a massive number of terminals, sharing a common wireless channel in an uncoordinated fashion. Due to these features, the true potential of blockchain in this context is still elusive, and many open research questions remain. An efficient and viable implementation of the technology calls for dedicated studies to understand the key performance tradeoffs arising in wireless IoT networks.

Key tasks:

  • familiarise with the blockchain protocol and with its applications to IoT
  • study, by means of network simulations, the performance of blockchain in a wireless IoT setup
  • identify and investigate the fundamental trade-offs that arise

Your qualifications:

  • good knowledge in the field of wireless communications, with focus on MAC protocols
  • programming experience in Matlab and/or C++
  • enthusiast of working in an international environment

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (m/f/non-binary). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
