Abstract-Short range ad-hoc wireless networks can be used to deliver streaming multimedia for information, entertainment and advertisement purposes. To enable short-range communication between various devices, the Wi-Fi Alliance proposed an extension to the IEEE802.11 Wi-Fi standard called Wi-Fi Peer-to-Peer (P2P). It allows compliant devices to form ad-hoc communication groups without interrupting conventional access point-based Wi-Fi communication. This paper proposes to use Wi-Fi P2P connectivity to distribute streaming multimedia in ah-hoc formed user groups. The exchange of multimedia data is performed by forming an overlay network using Peer-to-Peer Streaming Peer Protocol (PPSPP). In order to make PPSPP function over WiFi P2P connections, this paper proposes a number of changes to the protocol. The performance of the proposed system is evaluated using a computer networks emulator. The evaluation is done by streaming Live and Video-on-Demand multimedia among the different size user groups and observing the streaming multimedia Quality-of-Service parameters.

“…In this paper, echoing to this technical trend, we attempt to realize real-time group video sharing among multiple mobile nodes connected by Facebook OSN friendship. The real-time video sharing feature is utilizing MOVi+ (Mobile Opportunistic Videoon-demand Plus) [1][2][3] that coordinates the segment-based scheduling among participating mobile nodes. That is, the centralized MOVi+ Coordinator opportunistically schedules the segment-based real-time sharing of video contents among mobile nodes 1 of selected Facebook group.…”

The exploding growth of OSNs (Online Social Networks) is a common trend in current mobile Internet era. In this paper, by linking the features of Facebook OSN and MOVi+ (Mobile Opportunistic Video-on-demand Plus) [1-3], we realize real-time P2P video sharing among mobile nodes. The realized prototype implementation clearly verifies the convenience and economic feasibility of OSN-initiated application development.

Multimedia data have become popularly transmitted content in opportunistic networks. A large amount of video data easily leads to a low delivery ratio. Breaking up these big data into small pieces or fragments is a reasonable option. The size of the fragments is critical to transmission efficiency and should be adaptable to the communication capability of a network. We propose a novel communication capacity calculation model of opportunistic network based on the classical random direction mobile model, define the restrain facts model of overhead, and present an optimal fragment size algorithm. We also design and evaluate the methods and algorithms with video data fragments disseminated in a simulated environment. Experiment results verified the effectiveness of the network capability and the optimal fragment methods.
