For municipalities, it is often challenging to achieve the bandwidth and coverage that is necessary for many of the envisioned network services. At the same time, Wi-Fi-sharing communities achieve high bandwidth and good coverage at a very low cost by capitalizing on the dense deployment of private access points in urban areas. However, from a technical, conceptual, and security perspective, Wi-Fi sharing community networks resemble a patchwork of heterogeneous networks instead of one well-planned city-wide network. This patchwork character stands in stark contrast to a uniform, secure platform for public and commercial services desirable for the economic success of such a network. Hence, despite its cost-efficiency, the community-based approach cannot be adopted by municipalities easily. In this paper, we show how to realize municipal wireless services on top of a Wi-Fi-sharing infrastructure in a technically sound and economically attractive fashion. In particular, we focus on how to securely provide services to mobile clients with and without client-side software support. Our solution cleanly separates the roles of controlling and administering the network from providing bandwidth and wireless access. With this separation, commercial ISPs and citizens with their private Wi-Fi can contribute to the network infrastructure. This allows municipalities in turn to focus their resources on municipal wireless services. mobile_access http://www.comsys.rwth-aachen.de/fileadmin/papers/2010/2010-heer-icc-pisa-sa.pdf Print IEEE Press

The goals of these networks are to bridge the digital divide, stimulate innovation, support economic growth, and increase city operations efficiency. While establishing such urban networks is financially challenging for municipalities, Wi-Fi-sharing communities accomplish good coverage and ubiquitous Internet access by capitalizing on the dense deployment of private access points in urban residential areas. By combining Wi-Fi communities and municipal Wi-Fi, a collaborative municipal Wi-Fi system promises cheap and ubiquitous access to mobile city services. However, the differences in intent, philosophy, and technical realization between community and municipal Wi-Fi networks prevent a straight-forward combination of both approaches. In this paper, we highlight the conceptual and technical challenges that need to be solved to create collaborative municipal Wi-Fi networks. mobile_access http://www.comsys.rwth-aachen.de/fileadmin/papers/2010/2010-heer-percomws-collaborative-municipal-wi-fi.pdf Print IEEE Press
