摘要:

60GHz毫米波无线个域网(WPAN)中具有严格QoS要求的多媒体流应用要求高速率、低延迟的数据传输以及低服务中断。在本文中,我们考虑的问题,鲁棒的中继放置在60 GHz的无线个域网。将业务从发射机设备中继转发到接收机设备,以促进i)用于非视距(NLOS)收发机对的主要通信路径,以及ii)用于视距(LOS)收发机对的辅助(备份)通信路径。我们制定了鲁棒最小中继布局问题和鲁棒最大效用中继布局问题的目标是最小化部署的中继数量和最大化网络效用,分别。有效的算法来解决这两个问题,并已被证明,以减少服务中断存在的移动主体,可能会阻止LOS路径的环境。

英文摘要:

Multimedia streaming applications with stringent QoS requirements in 60GHz mmWave wireless personal area networks (WPANs) demand high rate and low latency data transfer as well as low service disruption. In this paper, we consider the problem of robust relay placement in 60GHz WPANs. Relays forward traffic from transmitter devices to receiver devices facilitating i) the primary communication path for non-line-of-sight (NLOS) transceiver pairs, and ii) secondary (backup) communication path for line-of-sight (LOS) transceiver pairs. We formulate the robust minimum relay placement problem and the robust maximum utility relay placement problem with the objective to minimize the number of relays deployed and maximize the network utility, respectively. Efficient algorithms are developed to solve both problems and have been shown to incur less service disruption in presence of moving subjects that may block the LOS paths in the environment.
