Abstract
We Introduce cross-layer, distributed power control algorithms that guarantee maximum possible data throughput in multihop CDMA wireless networks. Throughput maximization, for given power budget, Is achieved by jointly performing dynamic routing and scheduling together with power control. The cross-layer interaction consists in differential queue length information, made available from the network layer, which Is exploited by the physical layer power control function. The proposed back-pressure power control algorithms operate in real-time, i.e. in parallel with system evolution, and achieve maximum throughput without knowledge of traffic statistics. © 2006 IEEE.
