摘要:

下一代无线服务的特点是各种各样的要求,以维持这一点,无线接入点需要定期探测网络中的用户。在这方面,我们研究了一种新的多臂强盗(MAB)设置,任务探测所有的武器定期跟踪最好的当前手臂在一个非平稳的环境中。特别是,我们开发的\texttt{TS-GE},平衡经典的汤普森采样(TS)的遗憾保证与广播探测(BP)的所有武器,同时为了积极检测奖励分布的变化。该算法的主要创新之处在于通过一个名为组探索(GE)的可选子程序来识别改变的手臂,该子程序按比例缩放为$K-$武装匪徒设置的$\log_2(K)$。我们描述了环境参数的漏检概率和虚警概率。我们强调的条件下,遗憾的保证\texttt{TS-GE}优于国家的最先进的算法,特别是,\texttt{ADSWITCH}和\texttt{M-UCB}。我们通过在两个无线系统应用中使用\texttt{TS-GE}来证明其功效-移动边缘计算(MEC)中的任务卸载和为同时无线信息和功率传输(SWIPT)而设计的工业物联网(IIoT)网络。

英文摘要:

Next-generation wireless services are characterized by a diverse set of requirements, to sustain which, the wireless access points need to probe the users in the network periodically. In this regard, we study a novel multi-armed bandit (MAB) setting that mandates probing all the arms periodically while keeping track of the best current arm in a non-stationary environment. In particular, we develop \texttt{TS-GE} that balances the regret guarantees of classical Thompson sampling (TS) with the broadcast probing (BP) of all the arms simultaneously in order to actively detect a change in the reward distributions. The main innovation in the algorithm is in identifying the changed arm by an optional subroutine called group exploration (GE) that scales as $\log_2(K)$ for a $K-$armed bandit setting. We characterize the probability of missed detection and the probability of false-alarm in terms of the environment parameters. We highlight the conditions in which the regret guarantee of \texttt{TS-GE} outperforms that of the state-of-the-art algorithms, in particular, \texttt{ADSWITCH} and \texttt{M-UCB}. We demonstrate the efficacy of \texttt{TS-GE} by employing it in two wireless system application - task offloading in mobile-edge computing (MEC) and an industrial internet-of-things (IIoT) network designed for simultaneous wireless information and power transfer (SWIPT).
