MobiClique is a mobile social networking software for mobile devices that allows people to manage their social network on their mobile device and to exchange messages with friends and communities of users sharing similar interests. MobiClique takes advantage of physical proximity to enrich the users social networks. It also exploits the device proximity and social relationships to disseminate content (i.e. messages) in a mobile ad hoc network in a store-carry-forward fashion without relying on any infrastructure.   Applications The core networking middleware of MobiClique builds on the Haggle prototype. In addition, we include the following applications: The mobile social networking application allows the user to interact with MobiClique’s underlying social graph. The application displays to the user the set of neighboring devices with their social profile and provides an interface to manage the user’s ad hoc social network (i.e. add or remove friends and change interests). The user is informed of the presence of a friend or a potential new friend by a sound or a vibration. The asynchronous messaging application allows friends to send messages to each other over the social network substrate. This application is modeled around a conventional instant messaging application and enables threaded discussions and file sending. The epidemic newsgroup application allows asynchronous discussions among multiple people sharing a specific topic of interest. This application is similar to the traditional “Usenet” messaging service. The messaging interface is the same as in the asynchronous messaging application, with the exception that message threads are displayed within the context of a particular interest group, rather than a particular friend. The ad hoc voting application lets you vote for your favorite talk, meal, or social event at SIGCOMM 2009. The voting results are collected opportunistically as people meet other people with new votes.   SIGCOMM 2009 Experiment We are performing together with the Haggle project a mobile social networking experiment with MobiClique during the SIGCOMM 2009 conference in Barcelona (17th - 21th August, 2009). The goal of the experiment is to collect data on real application usage, Bluetooth contact opportunities and opportunistic communications. The trace will be anonymized and made available later on CRAWDAD. For the experiment, we distribute to around 100 volunteers a smartphone that runs MobiClique. Each user is asked to carry the device during the conference and use the MobiClique application to interact with each others. The initial social profile will be bootstrapped using participants' real Facebook accounts (visible information can be chosen at initialization time). We will award 10 LG and 3 HTC smartphones to the most active participants in the end of the conference.   How to Participate to the Experiment? Join the MobiClique SIGCOMM 2009 group on Facebook. When you arrive to SIGCOMM, come to see us on our desk close to the registration area to get your device. To bootstrap your device, we will ask you to connect to your Facebook account once. We will fetch your id, basic profile information, the list of your groups and networks, and the list of friends. The profile information is uploaded to your device. You can edit the profile before it is uploaded on the device to exclude any details you do not want to be visible in the experiment. After the profile setup you are ready to go and start meeting new people, create new groups, send messages and give your opinion on various talks using the MobiClique applications. In case of problems or if you have any questions, we will present on our desk during the conference at least during the breaks. You can also post your questions and feedback to the Facebook group. Bring back your device before you leave the conference on Friday 21/9/2009 at latest!   Further Reading Anna-Kaisa Pietilainen, Earl Oliver, Jason LeBrun, George Varghese and Christophe Diot.
