Using the application of bluck data transfer, we investigate the performance of QoS-satisfied pathover for transport layer mobility scheme such as mSCTP in FMIPv6 envirmonment. We find that existing scheme has some defects in aspect of pathover and throughput. Based on this, we make a potential change to mSCTP by adding QoS-Measurement-Chunk, which is used to take into account information about wireless...
In this paper, we propose a novel error concealment algorithm for intra frames of h.264/AVC. By using the high correlation of adjacent frames sequence, the proposed algorithm performs quadratic interpolation to the error pixel value of the concealed intra frame from the corresponding pixels of the previously decoded frame and the adjacent blocks received correctly while remaining the least distortion...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
