A crowdsourced WiFi sensing system with an endorsement network in smart cities

As crowd-centric applications have attracted a lot of attention, this work exploits the crowdsourcing technologies to collect and share user experience of WiFi hotspots in an urban area. To address the trust issue, we incorporate an endorsement network into the system, where users can endorse others based on the reviews submitted by themselves. With the incentive endorsement network, our system can quantify the trustworthiness of data publishers to make the system more trustful. We have implemented our design as a mobile application for mobile devices to demonstrate how our system guides people to connect to WiFi hotspots and how the endorsement network works with the crowdsourced WiFi sensing system.
