To exploit multiuser spatial cooperative diversity, relay nodes can assist the transmission of signal from multiple sources to their corresponding destinations in order to combat the noise, the channel fading and the cross-interferences. In this work, we consider a network consisting of N source-destination pairs and a set of M relay nodes. We assume that a fixed total budget of transmit energy is...
We consider the problem of cross-layer utility maximization subject to stability constraints for a multi-commodity wireless network where all links are sharing a number of orthogonal channels. We assume a time slotted network, where the channel gains are changing randomly from slot to slot. The optimal cross-layer network control policy can be decomposed into three subproblems: 1) flow control at...
