We in this paper explore a new data dissemination framework in Mobile P2P networks. Previous works in the literature usually elaborated upon the reduction of dissemination frequency in the network. However, many important and practical issues remain unresolved. First, the success of the system design usually relies on the support of other hardware components such as GPS, causing the extra power consumption. In addition, the property of the physical media used to make the ad-hoc network is not well discussed in the system. The system which assumes all users can access WiFi or 3G everywhere will limit the grow of the system popularity. Most importantly, the user preference is not considered, and each peer will receive and help to broadcast all messages whether the user is interested in. In this paper, we propose the MobiPAD framework, which the current stage concentrates on applications of data dissemination in student communities. The MobiPAD framework is built based on Bluetooth since Bluetooth is low power consumption and high penetration rate, and is suitable for students without the expensive 3G or WiFi accessibility. We also consider preference-aware disseminations to support various user preferences in the Mobile P2P network. The fairness issue is considered in the model, meaning that users who receive more interesting messages should contribute more message retransmission than users who wonder to receive few messages. The basic MobiPAD platform for student communities is also discussed in the paper, to show its possibility for further use.
