Research topics

Since 2002, I have been a member of the Wireless Networks Group (WNG).

At the early stages of my academic career, I focused mainly on performance improvement of Internet protocols over WWAN technologies such as GPRS or UMTS. Later, I focused on the broad area of design and evaluation of wireless multihop networks, including mesh networks, ad-hoc networks and sensor networks, with a special emphasis on protocols and optimizations developed by the IETF for the Internet of Things, and the application of these technologies to several areas such as smart cities, home automation, etc. You may be interested in visiting the complete list of publications I have (co)authored.

Some technologies, protocols or areas I am interested in include:

    • Wireless Sensor Networks

    • Wireless Mesh Networks

    • IEEE 802.15.4, Bluetooth Low Energy, ZigBee and other (generally, wireless) low-power technologies.

    • IP-based protocols for the Internet of Things (e.g. 6LoWPAN, RPL, CoAP, etc.)

    • MANET routing protocols (e.g. AODV, OLSR...)

    • Routing metrics for wireless multihop networks (e.g. IEEE 802.11-based mesh networks, IEEE 802.15.4-based sensor networks, etc.)

    • IEEE 802.15.7 - Visible Light Communication (VLC)

    • LPWAN: SIGFOX, LoRaWAN, IETF solutions for LPWAN, etc.

I am interested in mathematical analysis, simulation-based studies and experimental studies.
