They got the award together with Olav N Østerbø from Telenor Research at the international conference held in Milan, Italy on 7-9 July 2020.
Due to COVID-19, the conference was held online, and Ashish presented his and his colleagues paper virtually.
The best paper award is based on the votes casted by the conference chair and the reviewer committee, and is an opportunity to recognize outstanding papers presented at the conference.
Spectral and energy efficiency in next-generation IoT networks
Meeting the capacity and energy demands of the Internet of Things (IoT) devices and networks is a challenge that needs to be resolved.
Thus, efficient utilization of the frequency spectrum and energy efficient data transmission are the two key requirements among the various challenging requirements of 5G and next-generation networks.
New energy and spectral efficient protocols to ameliorate the capacity and energy demands of massive IoT networks need to be designed.
In this regard, the OsloMet researchers investigate the performance of device-to-device (D2D) aided IoT Relay NOMA-SWIPT where the relayed communication is supported in the presence of direct links.
NOMA-SWIPT system provides an effective strategy to improve the achievable rate and energy efficiency of the system compared to a traditional orthogonal multiple access system.
The reason they have considered a D2D user in the considered system is to assist the energy harvesting based relay node for offloading its data traffic and thereby further enhancing the spectral efficiency of the considered system.
Their results demonstrated that, by having a direct link and using the maximal ratio-combining scheme for a single user in the proposed NOMA-SWIPT system, the achievable rate of the whole system can be improved.
Five best papers of 207
The conference had 207 research paper presentations and five best papers were awarded.
The committee of four reviewers gave the article of Ashish Rauniyar, Paal Engelstad and Olav N Østerbø very good comments as a good contribution in the field.
Encouraging to work harder
‘It makes me feel happy winning this award in an international conference, because it is good for my academic career. It is encouraging me to work harder and continue my research work,’ says PhD student Ashish Rauniyar.
His research also gave him a great experience earlier. In January 2020, he was selected as a Global Young Scientist for the prestigious Global Young Scientist Summit (GYSS) in Singapore January 14-17, 2020.
He has also won Best Paper Award at the IEEE 28th International Telecommunication Networks and Applications Conference in Sydney, Australia in November 2018.
Ashish is finishing his PhD scholarship in October 2020, and wants to continue his research.
