LIN, Wensheng, Security and Networks Area, received the IEEE Nagoya Section Conference Presentation Award 2019

Mr. LIN, Wensheng, (3rd year doctoral student in MATSUMOTO Lab of Security and Networks Area), received the IEEE Nagoya Section Conference Presentation Award 2019 for his paper presented at IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC).

"IEEE Nagoya Section Conference Presentation Award" is the award which the IEEE Nagoya Section selects and gives to university and graduate students who offer presentation at an international conference, which the IEEE hosts. The awards were available for the students' presentations that had been presented from April 1, 2018 until March 31, 2019. IEEE Nagoya Section decided to give the awards after careful consideration.

An Analysis of Performance Improvement by a Helper for Wireless Sensor Networks

Wensheng Lin, and Tad Matsumoto

Wireless sensor networks (WSNs) are the core component in the big data era. Due to the unreliable transmission environment, it is significantly useful to introduce a helper to refine the system performance. To begin with, we formulate the system model of WSNs as a problem of multiterminal source coding. Subsequently, we propose a 3D distributed compress-bin scheme and derive a corresponding inner bound by analyzing the expected rate-distortion. Finally, we investigate the performance improvement of a helper by comparing the derived inner bound with the Berger-Tung inner bound and through simulation. Both the theoretical bounds and simulation results indicate that a helper can obviously improve the system performance.

It is my great honor to receive the IEEE Nagoya Section Conference Presentation Award. I would like to express my sincere gratitude to my supervisor, Professor Tadashi Matsumoto, and other colleagues in Matsumoto's Lab. Moreover, the super computer in JAIST accelerate the simulations, and hence I can quickly obtain the results in this research. I will continue paying efforts to my research for more results.
