Since 2002, I have worked on the field of
wireless networking research in order to improve the performance of
cellular, Wi-Fi, ad-hoc and mesh networks. My current
research interests are:
Characterize the capacity bounds of multi-hop multi-rate wireless networks
Empirical study on the utilization of multi-user diversity to improve IEEE 802.11 MAC-based wireless LAN performance
