Telecommunications doctoral thesis earns Thailand Research Fund award


AIT graduate Dr. Areeyata Sripetch has received a second-level award from the Thailand Research Fund (TRF) for her doctoral thesis “Design of DWDM Networks for Power Utilities”. The awards are intended for Thai nationals who graduate with doctoral degrees. Dr. Areeyata Sripetch recently graduated from the telecommunications field of study at the School of Engineering and Technology. 
 
Five theses received top-level TRF awards this year, while 17 were awarded second-level awards. Dr. Areeyata’s thesis was one of two to earn second-level award distinction in the category of Engineering and Industrial Research. One thesis was awarded the top-level award. Dr. Areeyata was an advisee of Dr. Poompat Saengudomlert, who is an Assistant Professor of telecommunications.
 
The award-winning doctoral thesis considers a power utility company that tries to implement a communication backbone network whose links are optical fibers inside overhead ground wires on a power grid. Since power grid networks can often reach rural areas where other types of infrastructure networks cannot, implementing communication networks on top of power grids can serve as an effective means to reduce the digital divide between urban and rural environments.

The thesis provides a systematic approach (based on the optimization framework) to find a suitable communication backbone network topology that contains a set of nodes located at a subset of power substations. The resultant topology is computed such that each source-destination node pair is still connected, even though there is a link or node failure in the network. 
 
In addition to topology design, the thesis provides a solution-approach to computing routes and assigning wavelengths for traffic connections, taking into account the presence of optical amplifiers and physical layer constraints such as end-to-end signal-to-noise ratios.
 
The design-approach proposed in this thesis was applied to a realistic scenario based on the power grid topology of the Electricity Generation Authority of Thailand (EGAT). This section contains all the news and events. Please click on the links menu on the left for specific content.
