About the group

The WINET (Wireless Networks) group is one of the research groups in networking of the Computer Science Department of Federal University of Minas Gerais (more info). The WINET group participates in several research projects in the topic of wireless networks, developing new networking protocols as well as contributing to network management and security services for wireless communication. The group has several ongoing national and international partnerships, and our researchers publish in the main symposia and journals of the area.

Our research: The Internet of Wireless Things

WINET's research focuses on the Internet of Wireless Things. The internet of the future will be composed of billions of embedded devices as well as computers, interconnected by wireless links. In this scenario, it will be possible to monitor and interact with the physical environment through virtual means, by the use of small and embedded devices such as wireless sensor networks, networked actuators, as well as ordinary devices such as smartphones, tablets and notebooks. Further, networking equipment will be embedded in ordinary daily things, for example: RFID tags in medications, pallets, and food packages; home entertainment devices such as TVs, set-top boxes and stereos; safety and entertainment systems in cars and in public transportation; sensors in light poles, parking spots and semaphores.

Several heterogeneous and interconnected computational devices forming mobile wireless networks, together with new ubiquitous applications and services, will be part of our daily lives, e.g: home networks; personal networks for fitness and health monitoring; vehicular networks for traffic control; sensor networks for environmental studies and factory plant control; wireless mesh networks for Internet access on the go; ad hoc and DTN (Delay-Tolerant Networks) networks for the coordination of first responders, army and NGO personnel; participatory sensing, where citizens contribute and interact, providing their own observations on the environment and their surroundings.

In order to achieve this vision, several architectures, protocols and algorithms have to be developed. Those algorithms must be efficient, scalable, dependable, distributed and must support secure and autonomous operation of the devices. Further, we must ensure the interoperability of the Internet protocols with the protocols used by the wireless devices.

Lab location and resources

The WINET researchers have a lab room in the Exact Sciences building (Instituto de Ciências Exatas (ICEx)) of UFMG, dedicated to Math, Chemistry, Physics and Computer Science. For information on how to get there, click here.

Our laboratory has dedicated workstations, high-end servers for simulations, as well as equipment for experiments, test-beds and prototypes. As of now we have notebooks, PDAs, cellphones, mesh routers, WiFi access points, RFID tags and readers, as well as wireless sensor nodes of different families (see some of the pictures).
