연구주제

무선/유선 통신 네트워크를 위한 최첨단 기술 연구

WMNL(Wireless & Mobile Networking Laboratory)은 무선/유선 통신 네트워크를 위한 최첨단 기술을 연구하고 있으며, 5G/6G, WLAN, AI + networking, communications-computing convergence 등 다양한 분야를 다루고 있습니다. 또한, WMNL은 항상 혁신적이고 도전적이면서도 이론과 실제 사이의 균형이 잡힌 연구를 수행하고 있습니다.
특히, WMNL의 연구 주제들은 network optimization and scheduling, spectrum resource allocation, Quality-of-Service (QoS) and Quality-of-Experience (QoE) provisioning, EM analysis and modeling 등 다양한 영역에 걸쳐 있으며, 효과적이고 최선의 결과를 도출하기 위해 mathematical analysis and modeling, algorithm design, computer simulations, numerical analysis, experiments and measurement in real environments 등 여러가지의 접근법을 고려하고 있습니다.
