论文摘要
随着将来的无线通信越来越多，延长许多电池供电设备的寿命变得越来越具有挑战性，因为经常更换电池是一项繁琐的工作。混合访问点（H-AP）能够通过利用射频（RF）信号同时操作无线信息传输（WIT）和无线能量传输（WIT）。通过共同考虑用户的移动性和网站的受欢迎程度，我们专注于HAP部署计划的设计。具体而言，利用基于网格的城市街道的移动性模型来表征用户的动作。基于这种移动性模型，首先分析了部署网站受欢迎程度对机智和湿效率的影响。然后，提出了一个HAP部署计划，以达到机智和湿效率之间达到平衡的平衡，这被视为B部署方案。仿真结果表明，B部署方案对于满足机智和湿效率的各种要求更加灵活。
With the wireless communication being more various in the future, it's becoming challenging to prolong the lifetime of many battery powered devices, since frequently replacing their batteries is a cumbersome job. An hybrid access point (H-AP) is capable of simultaneously operating wireless information transfer (WIT) and wireless energy transfer (WET) by exploiting the radio frequency (RF) signals. By jointly considering both the mobility of the user and the popularity of the sites, we focus on the design of the H-AP's deployment scheme. Specifically, a mobility model of the grid based city streets is exploited for characterising the users' movements. Based on this mobility model, the impact of the deployment site's popularity on the WIT and WET efficiencies is firstly analysed. Then, an H-AP deployment scheme for striking a balance between the WIT and the WET efficiencies is proposed, which is regarded as the B-deployment scheme. The simulation results demonstrate that the B-deployment scheme is more flexible for satisfying diverse requirement of the WIT and WET efficiencies.
