Research Interests

My research experience and interests span various topics in the area of wireless computer networking and data communication systems. Specifically, I focus on developing methods and protocols that provide next-generation wireless networks with the capabilities of: (1) Adaptive and dynamic bandwidth sharing and access to the limited spectrum/bandwidth; (2) Efficient use of the limited energy resources; (3) Reliable support of applications with Quality-of-Service (QoS) requirements; and (4) Robust tolerance of wireless link failures and breakages.
