Hang Li, Chuan Huang, Fuad Alsaadi, Shuguang Cui

摘要:

基于能量收集的通信因其广泛的应用和商业化的可行性而引起了人们极大的研究兴趣。在本文中,我们考虑在发射机的EH约束的无线通信。首先,对于延迟容忍的流量,我们调查的长期平均吞吐量最大化的问题和分析比较的吞吐量性能对传统电源支持的系统。其次,对于延迟敏感的业务,我们分析了中断概率通过研究其渐近行为在高能量到达率制度,其中的能量分集的新概念被正式引入。此外,我们表明,中断概率接近零的速度,称为能量分集增益,根据不同的电源模式。

英文摘要:

Energy harvesting (EH) based communication has raised great research interests due to its wide application and the feasibility of commercialization. In this paper, we consider wireless communications with EH constraints at the transmitter. First, for delay-tolerant traffic, we investigate the long-term average throughput maximization problem and analytically compare the throughput performance against that of a system supported by conventional power supplies. Second, for delay-sensitive traffic, we analyze the outage probability by studying its asymptotic behavior in the high energy arrival rate regime, where the new concept of energy diversity is formally introduced. Moreover, we show that the speed of outage probability approaching zero, termed energy diversity gain, varies under different power supply models.
