MCL research on Wi-Fi MAC design for its coexistence with Bluetooth was recently published by the IEEE Transactions on Computers (Vol 64, No. 2, 2015 February). This paper is entitled with “Coexistence Wi-Fi MAC Design for Mitigating Interference Caused by Collocated Bluetooth,” and co-authored by Dr. Chia-Chun Hsu, Professor David Wei of Fordham University, and Professor Jay Kuo.

Dr. Chia-Chun (Alex) Hsu, a former PhD alum of MCL, graduated from USC in 2007. He is currently an engineer at Mdiatek, Taiwan. Before joining Mediatek, he worked at HTC in Taiwan. His expertise is on the design of network protocols in Wi-Fi and LTE communication systems. Dr. David Wei is a Professor of Computer and Information Sciences at the Fordham University, Bronx, New York. Dr. Jay Kuo is the MCL Director.

The main contribution of this work is the development of a cross-layer adaptive packet fragmentation algorithm so as to reduce the effect of interference to the Bluetooth devices in the Wi-Fi network. It is an extension of an earlier paper published in the IEEE Wireless Communications and Networking Conference 2007 entitled with “A cognitive MAC protocol using statistical channel allocation for wireless ad-hoc networks.” This conference paper has many follow-up works as evidenced by its high citation number (around 200 times).
