使用网络共享优化网络以实现Internet访问

Optimizing Networks for Internet Access Using Tethering

Vandana Mittal, Sanjit K. Kaul, Sumit Roy

摘要:

我们调查的情况下,互联网接入到用户设备(节点)是只能通过蜂窝网络。然而,并非每个节点都可以直接连接到它。相反,一些节点可以使用网络共享通过WiFi连接到共享其Internet连接的节点。实际上,节点分为热点和客户端。热点是直接连接到蜂窝网络的节点,并且可以向通过WiFi连接的其他节点提供互联网连接。客户端仅通过热点连接到蜂窝网络。在这项工作中,我们考虑的问题,确定热点和客户端的分裂,以及它们之间的关联,最大化所有节点的速率的总和,受到约束,任何节点得到至少它得到的速率时,所有节点都直接连接到蜂窝网络。通过易处理的网络,我们提供了深入了解节点之间的WiFi连接和它们与蜂窝塔的链接速率之间的相互作用,最大化总速率的分裂,在少数情况下具有可证明的最佳分裂。我们提出了一种新的启发式方法来拆分任何网络,并通过模拟详细阐述了从网络共享中获得的收益。

英文摘要:

We investigate scenarios where Internet access to a user device (node) is available only via the cellular network. However, not every node may connect directly to it. Instead, some may use tethering to connect over WiFi to a node sharing its Internet connection. In effect, nodes split into hotspots and clients. Hotspots are nodes that connect directly to the cellular network and can provide Internet connectivity to other nodes to whom they are connected over WiFi. Clients connect to the cellular network only via hotspots. In this work, we consider the problem of determining the split of hotspots and clients, and the association between them, which maximizes the sum of the rates of all nodes, subject to the constraint that any node gets at least the rate it gets when all nodes are directly connected to the cellular network. Via tractable networks, we provide insights into the interplay between WiFi connectivity amongst nodes and rates of their links to the cellular tower, the splits that maximize sum rate, with provably optimal splits for a few cases. We propose a novel heuristic approach to split any network and provide a detailed exposition of gains available from tethering, via simulations.
