Xavier
Vilajosana Guillén

Xavier Vilajosana Guillen's research work focuses on the study of large-scale distributed systems including sensor networks, M2M mechanisms and the Internet of Things. Xavier is a member of various standardization bodies, including the IEEE and the IETF, where he works on the development of standards for low-power wireless networks. He is a specialist in the MAC layer, for which he has developed various TDMA and FDMA protocols. He has also developed data link layer services such as distributed schedulers and other approaches based on label switching on networks with very low energy consumption levels and significant computational constraints. He is a founding member of OpenWSN at the University of California, Berkeley. OpenWSN is an open-source project that fosters the use of standards to achieve energy-efficient, multi-hop wireless communications. Its main research areas are the development of low-power communication protocols, with an emphasis on standardization. He has implemented standards such as 6LowPan, RPL, RSVP and GMPLS as part of the OpenWSN project. He also specializes in system scaling mechanisms, distribution, replication and fault tolerance. In this context, he has worked on various transfer projects implementing data warehousing technologies based on key-value pairs. He is a member of the UOC's Wireless Networks Research Lab (WiNe). He is also a member of the IEEE and a visiting professor at the University of California, Berkeley.
