Research

Luca Bedogni research work focuses on the efficient utilization of White Space spectrum, particularly regarding the TV White Space scenario. He also worked on MAC protocols for Vehicular Networks, in the IEEE 802.11p and IEEE 1609.4 protocols.

He studies Machine-to-Machine communication over TV White Spaces, in the challenging indoor environments.

In addition, he also work on the possible utilization of TV Gray Spaces, focusing on the underlay spectrum access paradigm in Cognitive Wireless Networks, in which secondary devices might transmit on the same frequencies actually used by the primary users, by granting them a sufficient protection.

Vehicular Networks

During the first period of his PhD studies, he worked on efficient techniques to develop MAC protocols and enhancements for the IEEE 802.11p family and for the IEEE 1609.4 protocol. He enhanced a MAC protocol, called DBA-MAC, to distribute broadcast messages in dense scenarios for Vehicular Networks. He then continued on the same topic, proposing a method to improve the reliability and QoS of the IEEE 802.11p protocol, targetting the multi-channel scenario described by the 1609.4 protocol.

M2M communication

The core of his PhD thesis targets the utilization of TV White Space spectrum for M2M communications in indoor scenarios. Particular applications examples for this technology are the smart grid paradigm, the internet of things (IoT), and home appliances such as video streaming over the house. He uses and develops strategies and methods for Cognitive Wireless Networks to build networks of cooperating devices that operate in this challenging yet powerful spectrum band.
