A Constrained Resource Allocation Study for LOS MIMO Fading Ad-Hoc Networks
The authors study constrained resource allocation problems for MIMO wireless ad-hoc networks under LOS fading. By considering the tradeoff between the aggregate consumed power and throughput of such networks, they investigate the performance characteristics of a number of MIMO coding techniques, namely MRC, STBCs, and orthogonal STTCs. Their study shows that utilizing space-time coding techniques can decrease the power consumption and/or increase the achievable throughput of ad-hoc networks under loss constraints. Addressing the tradeoff between the achievable throughput as a metric of Quality of Service (QoS) and the consumed power under the presence of fading is arguably an important issue in ad-hoc networks.
