Outline of Research at the Start |
Underwater optical wireless communication (UOWC) is considered a potential candidate for B5G/6G networks. The major hurdle for practical and reliable UOWC systems is the complex characteristics of the underwater channel that depend on changeful environments ranging from shallow coastal water to deep oceans.To overcome the dynamics nature of the UOWC channel, we propose a flexible and reconfigurable design of the UOWC system exploiting the concept of intelligent reflecting surfaces (IRS), the spatial diversity gain of the MIMO technique to meet the requirements of the underwater channel.

Outline of Annual Research Achievements |
- Characterizing the key hurdles in implementing a practical underwater optical wireless communications (UOWC) system, including autonomous underwater vehicles (AUV) communicating with an onshore base station through relay nodes.
- Evaluating the end-to-end performance of this UOWC system under pointing errors while considering the depth-dependent characteristics of the underwater link. (Results to be published in the upcoming edition of IEEE flagship conference: IEEE VTC2024-Spring)
- Investigating the UOWC system performance by applying the derived analytical model to characterize the delay induced-fading resulting from the motion of AUV. (Results disseminated in IEICE UWC2024)

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The progress in research exceeded the initial expectation due to rigorous evaluation methods and a collaborative research approach, leading to interesting findings on the capacity and reliability of the evaluated underwater optical wireless communications (UOWC) system.
|
Strategy for Future Research Activity |
- Evaluating improvement in capacity and reliability within the underwater optical wireless communication (UOWC) system while exploiting the spatial diversity gain of multiple input multiple output (MIMO) technique.
- Based on the evaluation results: Proposing an optimized design for this MIMO-UOWC system using the concept of the intelligent reflecting surfaces (IRS) technology for increased flexibility and communication efficiency.
- The research results will be compiled and submitted to major journals and conferences in the field of UOWC.
