Abstract—DHTs have been recently used in Peer-to-Peer
(P2P) live streaming systems to improve video playback
continuity and data segment availability. However, existing
solutions are not especially optimized for live streaming
applications. There are still some challenging issues to be
addressed, especially the low search efficiency for time-sensitive
applications. In this paper, we propose an efficient one-hop DHT
lookup framework called Streaming DHT (SDHT), dedicated to
supporting media data compensation for real-time streaming
applications in P2P networks. SDHT framework includes an
One-hop DHT implementation solution Enhanced Event
Detection and Reporting Algorithm (EDRA+) and a distributed
Index Mapping and Management Mechanism (DIMM). We
conduct intensive simulation experiments based on OverSim to
validate the effectiveness of SDHT and evaluate its performance.
Numerical results show that SDHT can significantly improve the
searching efficiency and media data availability for live
streaming applications, with a low overhead.
Index Terms—Internet, peer-to-peer (P2P), live streaming,
one-hop DHT.
