Diurnal availability for peer-to-peer systems

Ensuring content availability in a persistent manner is essential for providing any consistent service over peer-to-peer (P2P) systems. This paper introduces an efficient protocol, called DATA, to design highly available P2P systems irrespective of peer uptime and churn. Our approach utilizes the diurnal pattern of globally dispersed peers to develop a grouping strategy where each group aims to ensure 24 × 7 data availability within the group. Simulation results reveal that our protocol converges fast and ensures high availability for each group with minimal overhead.
