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 demonstrated by the emergence of community-based wireless access schemes. In the authors' prior work they 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. Their system tries to match peer consumption with contribution and they have shown it to work well for city-scale Wi-Fi sharing communities.
