P2P live video streaming offers improved scalability, content serving capacity, robustness, and reduced buffer time when compared to streaming from centralized server. The existing overlay structures suffer from skewing due to the churn scenario. The proposed DNA structured overlay greatly increases the scalability and reduces the end-to-end delay The time taken for peer to get allocated in the overlay network is O(logn) where all the existing systems will take at-least O(n). In the proposed system, the message overhead is made O(1) which results in the reduction of end-to-end delay. © Springer Nature Singapore Pte Ltd 2021.
