Early Stage Researcher (ESR 14), PhD Student Position in the H2020 MCSA ITN “APROPOS”. Topic: Approximate Computing for Communications / Väitöskirjatutkija (Marie Sklodowska-Curie)

Tampere University and Tampere University of Applied Sciences create a unique environment for multidisciplinary, inspirational and high-impact research and education. Our universities community has its competitive edges in technology, health and society. www.tuni.fi/en

Applications are invited for 15 full-time PhD student positions (called Early Stage Researchers or ESR) for PhD degrees for 36 months. The positions are offered within the Approximate Computing for Power and Energy Optimisation (APROPOS) International Training Network action of the highly appreciated EU-funded Marie Skłodowska Curie grants (http://www.apropos-itn.eu). The positions are fully funded for a 36-month period. You can choose your position in one of 14 top-level universities and companies in Europe and complement your experience within periods from 3 to 9 months of cross-sector secondments by working with the highly committed industrial partners of the action. You are encouraged to apply for up to three positions within APROPOS network if you believe your profile is suitable for multiple topics. A separate application is needed for each position in case you apply for multiple positions.

APROPOS is an international, multidisciplinary and multi-sectorial training network programme on approximate computing. APROPOS is funded by the European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska Curie grant agreement No. 956090.

The ESR-specific project is described below. Please read the description carefully before applying.  We recommend you choose the position you apply for based on your technical profile and desired technical expertise, rather than based on the hosting location, as all positions involve high-level research mobility.

JOB DESCRIPTION

APROPOS will train 15 Early Stage Researchers to tackle the challenges of future embedded and high-performance computing by using disruptive methodologies. Following the current trend, by 2040 computers will need more electricity than the world energy resources can generate. On the communications side, energy consumption in mobile broadband networks is comparable to datacentres. To make things worse, Internet-of-Things will soon connect 20 to 50 billion devices through wireless networks to the cloud. 

APROPOS aims at decreasing energy consumption in both distributed computing and communications for cloud-based cyber-physical systems. We propose adaptive Approximate Computing to optimize energy-accuracy trade-offs. Luckily, in many parts of the global data acquisition, transfer, computation, and storage systems there exists the possibility to trade off accuracy to either less power or less time consumed – or both. As examples, numerous sensors are measuring noisy or inexact inputs; the algorithms processing the acquired signals can be stochastic; the applications using the data may be satisfied with an “acceptable” accuracy instead of exact and absolutely correct results; the system may be resilient against occasional errors; and a coarse classification or finding the most probable matches may be enough for a data mining system. By introducing a new dimension, accuracy, to the design optimization, the energy efficiency can even be improved by a factor of 10x-50x.  

APROPOS will train the spearheads of the future generation to cope with the technologies, methodologies, and tools for successfully applying Approximate Computing to power and energy saving. The training, in this first ever ITN addressing approximate computing, is to a large extent done by researching energy-accuracy trade-offs on circuit, architecture, software, and system-level solutions, bringing together world leading experts from European organizations. In addition, we will provide network-wide and local trainings on the substance and on the complementary skills needed in both industrial and academic work life.

ESR 14 work description: Low power mesh networks are a key technology in Internet of Things (IoT) domain, especially in systems including large number of devices in high densities. This far mesh technologies have been implemented on relatively simple radio transceivers, such as Zigbee and Bluetooth BT/BLE radios which limit e.g. the device-to-device distance and link reliability, and thus, overall system capabilities. Wi-Fi can be used in mesh configuration (IEEE 802.11s), but is heavily limited in scalability and power consumption due to IEEE 802.11 MAC and PHY design. More capable radios, such LTE-M type radios, have not really been used in low power, low cost mesh networks scope, but are used solely in star configuration in cellular networks. LTE-M type radios, however, provide superior link performance and reliability compared Zigbee, BT/BLE, and Wi-Fi. The drawback is higher power consumption and cost of the LTE-M radio chipsets. 

The work includes design, simulation, and prototyping of mesh protocols and algorithms on LTE-M type radios. The target is to minimize the power consumption and cost of the wireless devices by using approximate computing and other necessary techniques. Inside a device, the work concentrates especially on TDMA and FDMA MAC designed for mesh operation and its co-operation with an LTE-M type PHY (OFDM including HARQ). Although the main scope is not in the PHY, necessary approximation techniques in this layer will also be identified that support the target of overall device power and cost optimization. Also, analysis of partitioning the techniques to optimal processing blocks, such as application processor, modem host processor, and baseband processor, will be carried out. The impacts will be analyzed in mesh network level to assess the feasibility and performance in real large scale systems. 

The work will be done in tight co-operation with Wirepas R&D team developing the mesh protocol firmware and Wirepas’ semiconductor partners providing the radio chipsets. 

ESR 14 Objectives:

  • Demonstrate the energy-accuracy trade-offs in approximate MAC layer and other mesh protocol layers
  • Apply approximate computing to low-energy adjustable radio protocol design
  • Support the benchmarking activities

ESR Expected Results:  

  • Proof-of-concept implementation of adjustable receiver protocols 
  • Methods for designing low-cost approximating receiver protocols
  • Completion of the PhD/D.Sc.(Tech) at the hosting unit within 36 months

Planned secondment(s): TAU, supervisor Prof. Jari Nurmi, M24, 4 months and M40, 5 months for coursework, academic training, thesis writing, and aligning with the research outcome of Tampere Univeristy research on approximating hardware.

Supervisory team: 

  • Prof. Jari Nurmi (TAU), main supervisor
  • Prof. Elena-Simona Lohan (TAU), academic co- supervisor
  • Dr. Aleksandr Ometov (TAU), academic co- supervisor
  • Dr. Ville Kaseva (Wirepas), industrial co-supervisor
