摘要

在這個通訊科技快速發展的時代，新的技術不斷的出現並漸漸取代以往的科技，基礎的建設也是日新月異，因應新一代LTE-A網路以及蓬勃發展的車載通訊，需要大量的基地臺來確保網路通訊的品質，要如何佈建這些基地臺就是本文所討論的重點。
本文主要是在討論如何在一個未建設的區域設置新的基地臺，並且使建設的預算最小化還有基地臺涵蓋的範圍最佳化，以節省建設成本來達到最佳的涵蓋效果。本文中模擬了多種不同的地形以及配置不同的建設成本，並使用上數種不同的模擬方式來找到最佳的結果。
我們同樣也研究在三維空間中的最佳化配置法，如何在一棟建築物內設置最少的無線路由器，並使得整棟大樓都能夠使用無線網路。

In this paper we investigate the roadside unit (RSU) deployment problem in vehicle-to-infrastructure communications. While preparing for the new generation of vehicular communication era, there are many preparatory works we should do at first. The most important thing is to deploy enough roadside units. It costs a lot of money while building new RSUs in an uncovered area, so we propose a method to find the optimal placement of RSUs.
In this work we focus on the RSUs’ placement with the goal to minimize the total cost. We consider the deployment of RSUs with different cover ranges to cover all service areas. Some different constraints are considered to provide more realistic simulation results.
We also consider some RSU or WiFi APs’ deployment in a building. Unlike the RSUs’ placement with two dimensions in an area, it’s three dimensions deployment in a building.
