The CROMO (Crowd Data in the Mobile Clowd)  project is a CAPES COFECUB program held to accomplish a strong research collaborations between french and Brazilian partners (Inria Lille, Université Pierre et Marie Curie , Université de La Rochelle, Universidad Federal do Rio de Janeiro).

Mobile cloud computing is an emerging paradigm to improve the quality of mobile applications by transferring part of the computational tasks to the resource-rich cloud. The research challenges adresses by this project can be summarized as follows:

• Data sensing: choosing the most appropriate data sources with regards to an application of interest (e.g., car traffic in a given city), and pre-selecting the most meaningful data to send are challenges not fully investigated in the current literature.
• Mobile networking: analyzing all the available mechanisms for efficiently sending and receiving data from the cloud is also a challenge, since mobile cloud requirements are not totally identified yet.
• Cloud computing: processing data from multiple sources and retrieving useful information in a timely manner is another challenge, since there are no guarantees that all required data is indeed transferred to the cloud or that the cloud is always available for mobile users.
