easy-City
Fábio Pereira, João Barreto · 2011
This paper addresses the hard problem of route searching on public transport transportation. easy-City is a decentralized collaborative system that takes advantage of public transport users' mobility and observations to provide a route searching service. Users' mobile phones and deployed infra-structure devices establish a delay-tolerant network to efficiently disseminate information about routes and other events occurring on the public transportation network. We introduce a novel message dissemination protocol that exploits estimates of each user's future locations to make informed forwarding, message aggregation and buffer management decisions.
