WiNet’s research sits at the intersection of wireless networking, protocol design, and real-world constrained environments — from a sensor in a mine shaft to a nanosatellite in low Earth orbit. Below are the group’s current research directions, grounded in our recent publications; see Publications for the full list.

Direct-to-satellite IoT and space networking

Designing medium-access, synchronization, and channel models for IoT devices that talk directly to LEO nanosatellite constellations, and extending delay-tolerant and contact-graph routing concepts toward interplanetary and deep-space communication links.

Constrained IoT and LPWAN

Header compression (SCHC), fragmentation, and reliability mechanisms for constrained IoT traffic over LoRaWAN, Sigfox, and satellite links, including performance under intermittent connectivity.

Industrial and underground IoT

Wireless sensor network placement and propagation modeling for harsh RF environments such as underground mines, and sustainability-aware evaluation of IoT/network infrastructure (see our GEMINIS methodology work).

5G/6G radio access and transport performance

Congestion control and active queue management for fluctuating mmWave links, and their impact on real-time and adaptive video applications (e.g., QUIC-based streaming) in 5G-Advanced/6G networks.

Vehicular networking and road safety

Cooperative awareness and message dissemination for connected vehicles and vulnerable road users (pedestrians, cyclists) under C-V2X and 5G NR, including safety-message generation and beaconing strategies.

Internet standardization

Ongoing contributions to the IETF, including work on SCHC (Static Context Header Compression) and IP-based approaches for constrained and vehicular networks.

Group origins

WiNet was founded in 2014 at Universidad de Chile, where the group’s early work addressed heterogeneous vehicular networking, smart grid and AMI communications, cooperative cyclist systems, and HTTP/2 for IoT — several of which remain active threads today. That earlier chapter of the group’s work is preserved on the 2014–2022 archive.
