===== Denial-of-service attacks over wireless networks =====

\\
**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).
