Abstract

To alleviate energy hole problem inherent in static Base station (BS) scheme and extend network work of battery-restricted wireless rechargable sensor networks, a joint mobile data col-lection and adaptive charging scheduling (MDC-ACS) scheme based on virtual grid is proposed in this paper, aiming to achieve whole network energy balance and high charging effi-ciency. In MDC-ACS scheme, network is firstly divided into several grids and several rendezvous are determined using geo-graphic information. Then, mobile data collector (MDC) moves in grids for data collection within the application delay and moving trajectory is guided by rendezvous. Due to the limited battery capacity of mobile wirelsee charging vehicle (WCV) and its energy consumption while cruising, an adaptive charging schedule scheme is proposed for maximizing recharging benefit. With extensive simulation, we demonstrate that MDC-ACS scheme can achieve better charging benefit and reduce average charging delay.

可充电无线传感器网络的联合移动数据收集和能源供应计划

为了缓解静态基站(BS)方案固有的能量空洞问题，扩展电池受限无线可充电传感器网络的网络范围，本文提出了一种基于虚拟电网的移动数据采集与自适应充电调度(MDC-ACS)联合方案，以实现全网能量均衡和高充电效率。在MDC-ACS方案中，首先利用地理信息将网络划分为若干网格，并确定若干交会点;然后，移动数据采集器(MDC)在应用延迟内移动到网格中进行数据采集，移动轨迹由交会引导。针对移动无线充电汽车电池容量有限和巡航时能量消耗大的问题，提出了一种充电效益最大化的自适应充电计划方案。通过大量的仿真，我们证明了MDC-ACS方案可以获得更好的充电效益和降低平均充电延迟。
