乘客在整个城市上下班时享受浏览互联网和使用社交网络应用程序的乐趣。然而，并非总是能够随意上网。首先，在某些地区，蜂窝覆盖可能很差或根本不存在。第二，蜂窝通信对于人口的很大一部分来说可能是昂贵的。希望找到卸载部分蜂窝业务的方法。在本文中，我们研究了在巴西里约热内卢市建立延迟容忍车辆网络的可能性。为此，我们依靠大型移动数据集报告24小时内12，456辆公交车和5，833辆出租车的GPS位置。我们评估了车辆之间的数据传输可行性，并表明仅使用车辆，战略性放置的接入点和廉价的闪存驱动器，每天传输超过25 TB的数据是可行的。
Passengers enjoy browsing the Internet and using social networking applications while commuting throughout the city. Nevertheless, it is not always possible to access the Internet at will. First, cellular coverage can be poor or nonexistent in some areas. Second, cellular communications may be expensive for a significant share of the population. Finding ways to offload part of the cellular traffic is desirable. In this paper, we examine the possibility of creating delay-tolerant vehicular networks in the city of Rio de Janeiro, Brazil. To this end, we rely on a large mobility dataset reporting GPS positions of 12,456 buses and 5,833 taxis during a 24-hours period. We assess the data transmission viability between vehicles and show that it is feasible to transport more than 25 TB of data in a day using only vehicles, strategically placed access points, and cheap flash drives.
