提供無線接取服務的無人機自主佈建

Abstract

在災難發生基地台受損或是不容易架設基地台的地區，以無人機作為無線基地台是其中一個可行的方案。無人機所具備的高機動性，減少了部屬的成本並且可迅速的提供網路服務。然而如何有效的減少無人機的電量消耗，並且快速地找到能夠有效服務使用者的位置，是本篇論文主要探討的問題。文章提出兩個基於賽局理論的方法，讓無人機在不需要互相溝通的前提之下，從周遭所得到的資訊，自主性地找到並服務地面上的使用者。針對提出的方法，我們透過數學驗證方法的穩定性。最後經由實驗結果確認我們提出的方法改善了舊有方法的缺點，包含穩定性、效能以及能量消耗。

Using UAV (Unmanned Aerial Vehicle) as wireless access point is one feasible option for the area in which network infrastructure is damaged due to disaster or not easy to be built because of the constraint of terrain. In such scenario, UAV can rapidly provide network service and therefore reduce the cost of deployment. However, UAVs should effectively find a good location such that they are able to conserve more energy on serving users. In this thesis, we propose two approaches based on game theory. Our approaches allow UAVs autonomously adjusting their location based on local information. We verify our approach is able to stabilize. Several experiments have been conducted to show that our approaches are more cost-effective and efficient than existing approach.
