SMR: A Synchronized Multipath Re-broadcasting Mechanism for Improving the Quality of Conversational Video Service

摘要

Multipath broadcasting is the one solution for conversational video broadcasting to increase the bandwidth of end-to-end systems and increase the video quality. Conversely, traditional multipath broadcasting methods are not appropriate for conversational video service delivery due to the high amount of duplicated packets that causes the delay in service. In this proposed work, rebroadcasting technique is used to assure the reduced amount of delay with the low packet loss. Delay is the main problem of rebroadcasting technique. A Synchronized Multipath Re-broadcasting mechanism (SMR) is proposed to improve the performance of rebroadcasting. A lot of other mechanisms are implemented to rebroadcast the non broadcasting packets in a best way. SMR scrutinizes and evaluates the delay and bandwidth of every packet. SMR will differ for dissimilar structures of packet loss. At last, SMR rebroadcasts the important elements of video stream information over other path with available parameters of decoding limit, rebroadcasting interruption and feature of video flow. SMR is a dependable multipath rebroadcasting mechanism for conversational video service and is estimated by simulations. The Simulation results prove that SMR is an efficient way to increase the QoS for the broadcast of conversational video service.
