    Abstract: 在可充電無線感測網路(Wireless Rechargeable Sensor Networks)中，如何讓具有行動能力的感測器能夠在耗盡電量前回到充電站充電是一項非常重要的研究議題。在本研究中，我們提出一個透過連座式(Cascaded Movement)的移動方式來平衡可充電感測網路中行動感測器的電量消耗。在事件導向的無線感測網路中，場景中感測器的耗電量會因為事件發生的次數不同而有所不同。我們可以調度位於剩餘電量較低感測器周圍的感測器來進行協助，然後讓剩餘電量較低的感測器向充電站慢慢靠近，等到有閒暇的感測器能來替補位置時，就可以花費較少電量回到充電站為其充電。利用這種方法可以有效平衡網路的電量，讓電量較低的靠近充電站，電量充足的在離較遠的地區感測，這種方法可以有效延長整個網路的存活時間。我們經過模擬的實驗結果證明這兩種機制能有效的提升無線感測器網路的網路存活時間。
    The energy replenishment problem is an important issue in wireless rechargeable sensor networks (WRSNs). In this study, we address the energy replenishment problem with mobile sensor in WRSNs. To achieve energy balancing between mobile sensors, we propose an energy balancing algorithm based on cascaded movement. The proposed energy balancing algorithm can find a better cascading schedule for the cascaded movement. To replace mobile sensors with a low remaining energy level, we propose a redundant mobile sensors dispatch algorithm. The proposed redundant mobile sensors dispatch algorithm will dispatch fully charged redundant mobile sensors to mobile sensors whose energy should be replenished as soon as possible. This ensures that mobile sensors most in need of a recharge can return to the charging station first.
