dc.description.abstract	在無線感測網路中，無線感測器的位置資訊是非常重要的。在感測器被布置並且被定位之後，感測器的位置是要持續地去維護的。感測器可能會因為自然現象或是人為因素而從原來的位置被移動了，因此感測器回傳給Sink的資訊與其位置會不一致，甚至散播其錯誤的位置資訊到網路中而導致以地理為基礎的協定或應用發生問題。因此，在這篇論文中，我們提出了一個輕量的分散式方法來偵測被移動的節點。模擬的結果顯示我們的節點移動偵測方法能夠在無線感測網路中有效率的運作，通訊成本和準確率優於過去所提出的方法，特別是在大範圍節點移動的情況下。	zh_TW
dc.description.abstract	The location information of sensors is significant in Wireless Sensor Network (WSN). However, after deploying and localizing the sensors, the location of sensors has to maintain constantly. Sensors may be moved from their original location by the depredation of the enemy or natural phenomena, and further, sensors return the inconsistent information with their incorrect location to sink or spread the incorrect location to the network resulted in arising problem with geographic protocol or applications. Consequently, in this paper, we proposed a new light-weight distributed scheme which is utilized the movement before and after with different topology to detect moved nodes. The simulation results show that our scheme can cost a bit of communication overhead and has high detection rate especially with large scale node movement.	en_US
