The exponential growth in adoption of mobile phones and the widespread availability of wireless networks has caused a paradigm shift in the way we access the Internet. It has not only eased access to the Internet, but also increased users' appetite for responsive services. New protocols to speed up Internet applications have naturally emerged. The QUIC transport protocol is one prominent case. Initially developed by Google as an experiment, the protocol has already made phenomenal strides, thanks to its support in Google's servers and Chrome browser. Since QUIC is still a relatively new protocol, there is a lack of sufficient understanding about its behavior in real network scenarios, particularly in the case of wireless networks. In this paper we present a comprehensive study on the performance of QUIC in Wireless Mesh Networks (WMN). We perform a large scale measurement campaign on a production WMN to compare the performance of QUIC against TCP when retrieving files from the Internet. Our results show that while QUIC outperforms TCP in wired networks, it exhibits significantly lower performance than TCP in the WMN. We investigate the reasons for this behavior and identify the root causes of the performance issues. We find that some design choices of QUIC may penalize the protocol in WiFi, e.g., uncovering sub-optimal interactions of QUIC with MAC layer features, such as frame aggregation. Finally, we implement and evaluate our solution and demonstrate up to 28% increase in throughput of QUIC.

“…In the recent years, this technology matured, and the focus of research shifted to their application as CNs. CNs have been the subject of a series of works in the past years that had the goal of analysing their topological features [41] [21] [24] [8], their routing solutions [9] [42], and their social and management aspects [14] [43]. The only paper that deals with community networks and uses a similar approach is from Vega et.…”

A Community Network is a bottom-up network created by a community of people with the goal of gaining control of their communications and overcoming digital divide. Community Networks are blooming, they range from small ones (tens of nodes) to gigantic ones (tens of thousands of nodes). They are made primarily of wireless links but in some cases they mix wired and wireless technologies. Community Networks are generally unplanned and non-layered, and the community tries to mirror the same approach in its governance, avoiding unnecessary management structures and relying on selforganization and spontaneous interactions. Community Networks are Peer Production platforms, a community of people that pools resources and contributes to build a shared value. While this value is generally immaterial (as in WikiPedia) Community Networks instead realize a distributed, peer-to-peer physical communication network.This paper analyses ninux.org, the largest community network in Italy, and one of the eldest in Europe. The goal of the paper is to understand if the spontaneous growth of the network and the community leads to a technically robust network and a socially robust community, or it hides the presence of (potentially interdependent) points of failure. We will show that, in spite of the original motivations of the ninux community, the network is fragile under several aspects, and we suggest ways to improve it.

QUIC is a new transport protocol under standardization since 2016. Initially developed by Google as an experiment, the protocol is already deployed in large-scale, thanks to its support in Chromium and Google's servers. In this paper we experimentally analyze the performance of QUIC in WiFi networks. We perform experiments using both a controlled WiFi testbed and a production WiFi mesh network. In particular, we study how QUIC interplays with MAC layer features such as IEEE 802.11 frame aggregation. We show that the current implementation of QUIC in Chromium achieves sub-optimal throughput in wireless networks. Indeed, burstiness in modern WiFi standards may improve network performance, and we show that a Bursty QUIC (BQUIC), i.e., a customized version of QUIC that is targeted to increase its burstiness, can achieve better performance in WiFi. BQUIC outperforms the current version of QUIC in WiFi, with throughput gains ranging between 20% to 30%.
