The problem

How to collect data for human mobility analysis Where do people spend more time during

the day? Which are the most frequent routes used by

people? It is possible to suggest alternative and more

sustainable paths for daily trips Which could be the best decisions

concerning new computing infrastructures deployments?

Large data sets Extended periods of time

The Epi application

Explore people as sensors Laptop vs mobile phone

Social application Text messages sharing between users Collects information about nearby APs Privacy policy

Preserves normal spatio-temporal behaviour of users

Text messages sharing as a service reward Non-personalised advertisements through social

services (in July and October 2010) to attract users

Discussion

Users are more active close to advertisement periods Scalable solution for advertisement and

distribution? Improve users’ awareness about the

value of the data collected collaboratively Which should be the main characteristics of

a mobile sensing application? Open access/publication to/of the data

How to ensure privacy, trust and integrity?
