面向大容量飞行网络的路由感知网关布局

Traffic-aware Gateway Placement for High-capacity Flying Networks

André Coelho, Helder Fontes, Rui Campos, Manuel Ricardo

摘要:

无人机(UAV)能够在几乎任何地方运行并携带有效载荷,这使得它成为携带通信节点(包括Wi-Fi接入点(AP)和蜂窝基站(BS))的完美平台。这为部署飞行网络铺平了道路,使地面用户能够按需通信。尽管如此,飞行网络提出了重大挑战,以满足体验质量的期望。最先进的工作解决了这些挑战,但一直专注于路由和布局的无人机作为AP和BS服务于地面用户,忽略了回程网络设计。本文的主要贡献是一个集中式的流量感知网关无人机布局(GWP)算法的飞行网络与控制拓扑。GWP利用所提供的流量和飞行网络的未来拓扑的知识来实现具有足够高容量的回程通信路径。使用ns-3模拟评估了使用GWP算法实现的性能。所得到的结果表明,关于聚合吞吐量和延迟显着的收益。

英文摘要:

The ability to operate virtually anywhere and carry payload makes Unmanned Aerial Vehicles (UAVs) perfect platforms to carry communications nodes, including Wi-Fi Access Points (APs) and cellular Base Stations (BSs). This is paving the way to the deployment of flying networks that enable communications to ground users on demand. Still, flying networks impose significant challenges in order to meet the Quality of Experience expectations. State of the art works addressed these challenges, but have been focused on routing and the placement of the UAVs as APs and BSs serving the ground users, overlooking the backhaul network design. The main contribution of this paper is a centralized traffic-aware Gateway UAV Placement (GWP) algorithm for flying networks with controlled topology. GWP takes advantage of the knowledge of the offered traffic and the future topologies of the flying network to enable backhaul communications paths with high enough capacity. The performance achieved using the GWP algorithm is evaluated using ns-3 simulations. The obtained results demonstrate significant gains regarding aggregate throughput and delay.
