A Topology-Aware Improvement on Chord

Routing efficiency is the critical issue when constructing peer-to-peer overlay. However, Chord has often been criticized on its careless of routing locality. In this paper, we propose a topology-aware improvement on the basis of Chord, which focuses on achieving better routing efficiency. It has lower latency by appending a topology-aware Chord circle to divide topology regions. The simulation shows that the improvement has achieved lower latency per message routing.
