Securing Every Bit: Authenticated Broadcast in Radio Networks

Rachid Guerraoui, Seth Gilbert, Dan Alistarh, Zarko Milosevic

This paper studies non-cryptographic authenticated broad- cast in radio networks subject to malicious failures. We in- troduce two protocols that address this problem. The first, NeighborWatchRB, makes use of a novel strategy in which honest devices monito ...

Efficient MAC in cognitive radio systems: A game-theoretic approach

Jean-Pierre Hubaux, Mark Felegyhazi, Mario Cagalj

In this paper, we study the problem of efficient medium access control (MAC) among cognitive radio devices that are equipped with multiple radios and thus are capable of transmitting simultaneously at different frequencies (channels). We assume that radios ...
