Sentient Bikes for Collecting Mobility Traces in Opportunistic Networks

We study the problem of building low-cost city-wide location track-ing systems with the intention to provide a platform for large-scale human mobility data collection. We take the city-bikes as our first target, motivated by several social networking applications, and choose Cambridge in the UK as our pilot case. We highlight the main application requirements, discuss the practical design issues, and propose a system architecture based on a hybrid sensor net-work. 1
