An ECDD technique to optimize QoS in wireless overlay network for multipath video streaming

Multimedia applications over wireless networks are growing day by day. To provide better user experience the use of overlay network is the promising solution. However, maintaining overlay in wireless network is the challenging task which produces additional overheads. This overhead degrades the quality of the video transmitted over overlay networks. To overcome these issues ECDD model is proposed in this paper. mTreebone is used to build an overlay This model also adopts FEC scheme for error correction and video data is transmitted by using sub packetization method in multiple paths. The simulation results show the improved performance of the algorithm with respect to end to end delay and retransmission requests. Number of retransmission requests is reduced by 52.27% than SPMLD.
