Achievable Rates for the Three User Cooperative Multiple Access Channel
— For a three user Gaussian multiple access channel (MAC), we propose a new superposition block Markov encoding based cooperation scheme. Our scheme allows the three users to sim...

Bandwidth exchange: an energy conserving incentive mechanism for cooperation
Cooperative forwarding in wireless networks has shown to yield rate and diversity gains, but it incurs energy costs borne by the cooperating nodes. In this paper we consider an inc...
