This iOS application was developed to support the 2012 Annual Meeting of the American Society of Human Genetics (ASHG) by the Wireless Networking and Mobile Computing Laboratory (WineMocol), Memorial University of Newfoundland and by the Computational Genetics Laboratory (CGL), Dartmouth College and.
It turns out that the devices's capability of using the Bluetooth short-range radios also forms an example of Delay-Tolerant Network (DTN).
Collection and analysis of data yields interesting real-life observation for studying such networks.
The app can be downloaded from the Apple App Store

The iOS application runs on iOS version 5.0 or later.
It is for the conference attendees to enhance your meeting experiences.
It facilitates browsing information about presentations, workshops, tutorials, meetings, and keynote speeches.
It features a map user interface for users to find posters during the poster sessions.
By indicating whether certain events are of interest during browsing, a user can hop among conference events while being aware of time conflicts.
Users can also send generic messages or messages about events to share thoughts with other attendees over the air.
The app uses the Bluetooth radio on the iPhone to achieve short-range wireless communication.
Since it does not rely on any infrastructure at the conference venue, such as Wi-Fi access points or cellular base-stations,
it can function in a wider scope of settings.
The Bluetooth radio on-board of the iPad has a transmission range of up to 100 meters in a not-so-"noisy" environment.
At conference venues, however, its range will be a fraction of that.
In general, two devices can be out of range of each other frequently, depending on where the users are and how they move.
Thus, a device will "mechanically" transport messages from one location to another as its user moves around.
When the app detects other group members within range,
it swaps messages with them.
Apparently, messages delivered as such are not "instant".
One of the purposes of this app is for a scientific research on infrastructureless mobile social networking.
During its operation, it records how messages propagate among devices over time. Using this app, you are contributing to this study tremendously.
At the end of ASHG 2012, the application will upload a trace file of how messages propagate among devices at the ASHG venue.
Please rest assured that no personal data will be accessed by this application in any way.
And we appreciate your great help in our research on computer networking.
