利用上下文信息的节能资源分配

Energy-saving Resource Allocation by Exploiting the Context Information

Chuting Yao, Chenyang Yang, Zixiang Xiong

摘要:

随着智能手机市场的不断扩大,最近通过利用上下文信息来提高无线系统的能量效率已经受到关注。在本文中,我们设计了节能的资源分配政策,多个基站服务的非实时业务,利用三个层次的上下文信息,其中背景业务被假定为占用部分资源。基于完全未来信息下的总能量最小化问题的解,提出了一种上下文感知的基站休眠、调度和功率分配策略,该策略利用3个层次的上下文信息估计所需的未来信息。仿真结果表明,我们的政策提供了显着的收益比那些没有利用任何上下文信息。此外,可以看出,不同级别的上下文信息在节省能量和减少传输中断方面起着不同的作用。

英文摘要:

Improving energy efficiency of wireless systems by exploiting the context information has received attention recently as the smart phone market keeps expanding. In this paper, we devise energy-saving resource allocation policy for multiple base stations serving non-real-time traffic by exploiting three levels of context information, where the background traffic is assumed to occupy partial resources. Based on the solution from a total energy minimization problem with perfect future information,a context-aware BS sleeping, scheduling and power allocation policy is proposed by estimating the required future information with three levels of context information. Simulation results show that our policy provides significant gains over those without exploiting any context information. Moreover, it is seen that different levels of context information play different roles in saving energy and reducing outage in transmission.
