| Mobile phone has become indispensable electronic products in people’s lives. The functions of mobile phones are expanding. Nowadays the smart phones have integration of many functions like information communication, business management, entertainment and SO on, which are of great convenience to the people. The popularity of mobile phones makes the increasing demand of the phone functions.Nowadays, video playback on mobile phone is popular. There are several Internet-based video streaming technologies available. However, few has been developed specifically for mobile-to-mobile video sharing in a small area. As video streaming consumes a significant amount of extra CPU and power, the idea of turning a phone into a streaming server for video sharing is unpractical. This paper presents SyncShare, the mechanism for a Android mobile phone node to share local videos in real-time with other nodes in a wireless LAN via network coding. Video Segment for Synchronization (VSS) is the fundament of SyncShare for the real-time synchronization of video sharing. SyncShare is implemented as a smart phone application that allows its users to share a video synchronously within a wireless LAN. The synchronization performance has been evaluated in experiments by measuring the energy capacity, the CPU usage as well as the delay time for synchronization in coding and non-coding schemes. Besides, we also measure the difference in energy consumption and CPU usage between the coding and non-coding cases. Results show that with SyncShare mechanism, average delay time can be reduced with coding strategies. |
