Node cooperation in wireless communication networks can overcome several of the limitations introduced by the wireless channel, such as fading, attenuation, susceptibility to eavesdropping and collisions. This talk presents our research results in the area cooperative communications. First, the talk explores cooperative beamforming for reliable transmission of information over long distances in an energy and cost efficient fashion. Second, it explores the role of cooperative transmissions in guaranteeing secure communications without the use of cryptography. In particular, it presents an information theoretic framework for optimizing secrecy capacity in the presence of one or multiple eavesdroppers. Third, it explores collision resolution via cooperative retransmissions and presents some research results showing that this approach can be the basis of new cross-layer protocols that can sustain high throughput while enjoying power savings.
