Abstract：Recent technological advancements in wireless infrastructures and hand-held devices enable mobile users to enjoy the rich Internet contents anytime and anywhere. However, the Internet is not designed for real-time streaming. Multimedia content streaming usually presents several Quality of Service (QoS) requirements and differs from traditional file sharing in a number of key distinguishing features. Thus, how to evaluate and improve mobile video system performance has become an important issue. Besides, with diversification of distribution services, Multi-View Video (MVV) content distribution service will become popular in the future. As a result, adjusting the current scheme which evaluates and improves mobile video performance to fit the MVV is also a big challenge today.

As a significant element in computer-aided design, 3D model is widely used in various fields, including mechanical manufacturing, biomedical engineering, architectural design, etc. However, how to reconstruct 3D model based on the current mobile Internet is quite a big issue. The main problem which should be concerned is how to reduce the waiting time and wasted energy, while ensuring models' quality. We focus on pursuing the tradeoff between the above two aspects by taking advantage of mobile Internet. Based on the basic structure of the existing Internet and the essence of 3D model reconstruction, both the effectiveness and the efficiency can be achieved.
