Universal Internet access has become critical to modern life, leading to many explorations of approaches to increase its availability. In this paper we report on a study of one such approach, PAWS, that seeks to understand the technical and social constraints of providing Internet access, free at the point of use, by sharing existing broadband subscribers' connections. We elaborate the technical and social context of our deployment, a deprived neighbourhood in a medium-sized British city, and discuss the constraints on and resulting architecture of this system, including the authentication and security mechanisms necessary for a service of this kind. We then report on the use of our deployment over a period of seven months from July 2013 to February 2014, including analyses of the performance and usage of the network. Our data show that PAWS is socially and technically feasible and has the potential to provide Internet access economically to many who are currently digitally disenfranchised.However, doing so requires overcoming numerous challenges, both technical and social.

“…A PEER-TO-PEER WI-FI SHARING SCHEME Our system [5], which we extend in this paper, is based on the concept of sharing wireless Internet bandwidth in a reciprocal manner; one shares his Internet connection with anonymous passers-by over Wi-Fi with the anticipation that he will enjoy the same benefit from another peer when mobile. Private WLAN owners have an incentive to contribute Internet bandwidth, given that they value much the mobile network access that they will enjoy as good contributors.…”

“…1 shows the interaction between entities during a roaming session. Note that this requires the extension of the original protocol [5] with new messages: WARREQ (WARranty REQuest) is used to request SPs to warrant for a roamer asking for service and contains the identity of the user. When its sender is the RR of the contributing AP, it also contains the identities of the SPs belonging to the user's home region.…”

Abstract-With the low installation and maintenance cost of IEEE 802.11-based equipment, dense Wi-Fi deployments are a reality, especially in today's urban areas. This vast number of WLANs can be exploited to achieve low-cost ubiquitous wireless Internet access, which is also demostrated by the emergence of community-based wireless access schemes. In our prior work we have developed a reciprocity-based peer-to-peer architecture for Wi-Fi sharing, where peers provide free Wi-Fi access to others in order to enjoy the same benefit when they are away from their own Wi-Fi network. Our system tries to match peer consumption with contribution and we have shown it to work well for city-scale Wi-Fi sharing communities. However, when attempting to roam outside the city boundaries, the statistics are such that there is typically a lack of consumption-contribution information between consuming and providing members, which hinders the system's scalability. In this work, we extend our architecture with global-scale roaming capabilities by relaxing the requirement for full decentralization. In particular, we exploit special trusted super-peers which act as representatives of different Wi-Fi sharing communities (e.g., communities of different geographical regions) and which mediate transactions when there is insufficient information about peer contribution history. Extensive simulations show that this super-peer-assisted approach can significantly enhance the system's performance in terms of roaming coverage.
