Resilient and Real-Time Wireless Communications

When: Tuesday, 2013-Feb-05, 11h30-12h00
Where: FCUL-DI, room C6.3.38
Presenter: Jeferson Souza

Wireless communications are susceptible to numerous sources of interferences such as external electromagnetic waves, obstacles in communication path, or even glitches in the network device circuitry. These kind of interferences may disturb the network operation, causing node and frame errors and imposing dependability and timeliness issues, which may imply temporal hazards to networked real-time systems. In this talk we present a bottom-up approach to enhance the dependability and timeliness properties of wireless communications, therefore making wireless networks more resilient against network errors. An architecture dubbed Resilient and Real-Time Medium Access Control (${\cal R}2{\cal T}$-MAC) is presented, emphasizing the relationship between its internal components and the compliance with existent communication standards such as IEEE 802.15.4 and IEEE 802.11p.
