In this work, we propose an effective live video streaming system, which exploits path diversity over heterogeneous wireless networks. Basically, fountain code is employed to efficiently integrate multiple paths and provide the error resilience for the live video streaming of high quality. In the proposed system, the path selection algorithm is designed to maximize the target video encoding rate while...
Network coding is a highly efficient data dissemination mechanism for wireless networks. Since network coded information can only be recovered after delivering a sufficient number of coded packets, the resulting decoding delay can become problematic for delay-sensitive applications such as real-time media streaming. Motivated by this observation, we consider several algorithms that minimize the decoding...
Recently, distributed space-time coding over half duplex wireless relay networks has been proposed to achieve higher diversity at the receiver. The use of orthogonal and quasi-orthogonal designs in such relay networks has the advantage of providing maximum diversity at a low decoding complexity. However, similar to their originating space-time codes, these designs are restricted in terms of rate and...
