With a sudden surge in demand for live video streaming using peer to peer (P2P) network, there has been a rise of traffic in media transmission applications that employ this P2P approach.P2P is a decentralized media communication method which is more cost effective, and scalable.However, the traditional peer to peer network architecture has several limitations, and overlay construction is one of them.The two different unstructured overlay approaches like tree and mesh have already been discussed.This paper gives a detailed comparison of various overlay approaches in P2P networks.We have also proposed and implemented a utilization based hybrid overlay approach for the P2P network.The two crucial parameters which are primarily considered while overlay construction is: peer upload bandwidth and peer resource utilization.For the purpose of verifying our approach, we have done a comparative analysis of the proposed utilization based approach with the popular DenaCast approach.The different QoS parameters like start-up delay, playback delay, end to end delay, frame loss ratio are used for verifying our approach.The simulation results presented in this paper provide better network performance and quality of video at receiver side.
