Streaming high definition video over heterogeneous wireless networks(HWN)

摘要

Video transmission over the heterogeneous networks faces many challenges due to available bandwidth, link delay, frame lost, throughput, reliability, network congestion. In video streaming it is important that the video stream must reach the users within allocated time and also without errors in video frames which leads to packet loss. Hence to avoid the packet loss and to enhance the Packet Delivery Ratio(PDR) and Throughput of the networks a modified Forward Error Correction mechanism was proposed by considering the feedback information(frame count, buffer status, round trip time(RTT)). Simulation results compares the performance in terms of packet delivery ratio(PDR), throughput and handover delay under various video packet rate and packet intervals.
