collection environment

The trace was collected at the University Politehnica of Bucharest, with the 72 participants being students from the facility, as well as teachers and assistants.

network configuration

The network formed by the devices was an opportunistic networks where some nodes are also socially connected, and have common interests.

data collection methodology

Collected using an Android application entitled HYCCUPS Tracer http://hyccups.hpc.pub.ro, with the purpose of collecting contextual data from Android smartphones. It was ran in the background and collected availability and mobile interaction information such as usage statistics, user activity, battery statistics, or sensor data, but it also gathered information about a device's encounters with other nodes or with wireless access points. Encounter collection was performed using AllJoyn. The data was collected by constructing and deleting wireless sessions using the AllJoyn framework based on WiFi. Tracing was executed asynchronously. By analyzing the participants' Facebook profiles, the social connections matrix was extracted, as well as the users' interests.

sanitization

The data was anonymized by assigning a random ID to each user in the network, starting from 1 up to 73. The same IDs were used for tracing the social connections and user interests. Interests were also anonymized by replacing them with integer IDs from 1 to 5. No private data is part of the trace. Some trace participants did not have a Facebook account, so their social and interest information is not present.

disruptions to data collection

Some participants did not have Facebook accounts, so their social network and interest information is missing. Some of them did not register contacts, because they did not have their WiFi on or did not attend courses at the facility.

limitation

AllJoyn WiFI contacts can only be collected when the two users are connected to the same wireless access point at the same time, since the connection is created through the AP. For this reason, contacts in this trace have been collected only when an experiment participant had the WiFi on and was connected to an AP.

note

For simulations of the trace, we used the MobEmu opportunistic network simulator https://github.com/raduciobanu/mobemu, which can replay the trace and apply a desired routing or dissemination algorithm.
