Packet Loss Modeling for Perceptually Optimized 3D Transmission

Transmissions over wireless and other unreliable networks can lead to packet loss. An area that has received limited research attention is how to tailor multimedia information taking into account the way packets are lost. We provide a brief overview of our research on designing a 3D perceptual quality metric integrating two important factors, resolution of texture and resolution of mesh, which control transmission bandwidth. We then suggest alternative strategies for packet 3D transmission of both texture and mesh. These strategies are then compared with respect to preserving 3D perceptual quality under packet loss in ad hoc wireless networks. Experiments are conducted to study how the time between consecutive packet transmission and packet size affects loss in wireless channels. A preliminary model for estimating the optimal packet size is then proposed
