Hybrid ARQ has been shown to be an effective strategy to improve the performance and capacity in wireless networks. In this paper, we present novel and simple feedback hybrid ARQ schemes with adaptive modulation for cooperative wireless networks. The proposed scheme combines the retransmission mechanisms, incremental relay and adaptive modulation. For more tractable analysis, we derive closed-form...
This work presents a novel adaptive cooperation scheme that takes both the channel state information and residual energy information into account to prolong the network lifetime while meeting the transmission rate requirement of destination. In order to achieve this aim, we will select the relay with the best instantaneous weighted channel conditions by attributing a weight coefficient to each relay...
