Boris Bellalta is a Lecturer in the Department of Information and Communication Technologies at Universitat Pompeu Fabra (UPF). He obtained his degree in Telecommunications Engineering from Universitat Politecnica de Catalunya in 2002 and the Ph.D. in Information and Communication Technologies from UPF in 2007.
His research interests are in the area of communication networks, with emphasis on the design and performance evaluation of medium access control (MAC) protocols for Wireless Networks. Specifically, Boris's research focuses on the design of new MAC protocols for Wireless Networks that efficiently exploit some of the most recent advances in wireless communications, like spatial multiplexing and dynamic spectrum access techniques.
There are many open research challenges to be addressed in the area of Multiple Access Communications in Wireless Networks, mainly because the number of communicating objects and new applications that use the unlicensed radio bands to send and receive data is increasing every day. These objects range from small sensors that transmit sporadically, to High Definition audio/video players that require a large bandwidth, or to Wifi smart-phones and laptops, which access the Internet through deployed Access Points or just communicate among themselves in an ad-hoc fashion. In such crowded and heterogeneous scenario, where multiple different wireless networks coexist, to achieve an efficient use of the spectrum resources, new principles such as adaptation to a high-dynamic environment and the ability to cooperate with others have to be considered in the design of new communication protocols.
