Abstract
Nowadays video streaming extends its applications to various multimedia services. The extremely challenging Over-The-Top (OTT) multimedia application create enlarged challenges to Internet Service Providers (ISPs) in assuring a realistic Quality of Experience (QoE) to their clients due to a require of flexibility, quickness and scalability in established networks. Here, we focus on reducing the buffer size of video and its impact on QoS parameters such as Packet Delivery Ratio (PDR), Throughput, End-to-End Delay and Energy have been evaluated. The work presented in this paper has focused on the simulation of video streaming over three video topologies (MP4, HD720 and HD1080 pixels) using RTP protocol integrated with RLNC over a Cognitive radio network. The system has been implemented and tested under a simulation environment by using the NS2 simulating tool. The QoS metrics for each video topology are carried out by employing 20 to 300 numbers of nodes over some time.
