radioActive WiFi Sharing for Autonomous Peers

WiFi sharing communities offer an attractive alternative to commercial hot-spots and cellular networks for users who seek Internet access while being away from home. The growing number of mobile devices with Internet usage capabilities has formed a basis for the establishment and growth of several such communities. However, critical security problems exist in all current WiFi sharing approaches because they employ a central operator. We show how to overcome these issues by decentralizing the community's organization structure and present radioActive WiFi, a system that implements this approach.
