General description

Wireless networks are specially vulnerable to attacks by malicious nodes since the communication is over the air and hence the legitimate transmitted signal is mixed with jamming signals. The question addressed by this project is in the context of wireless relay networks where there are a set of authenticated helper (relay) nodes that facilitate communication between a source and a destination. These helper nodes attempt to maximize throughput between the source and destination while protecting it from malicuous transmissions by jamming nodes.

Goal

The trade-off between throughput and resistance to these denial-of-service attacks is the main question addressed by this project. This develops on recent ideas on wireless networks developed (see http://licos.epfl.ch/index.php?p=research_projWNC).
