MChord: Chord Algorithm Based on Limited Multicasting

Abstract

Chord is known to be limited in routing efficiency since all nodes are on the overlay without considering the underlying network topology. In this paper, a Chord routing algorithm based on limited network layer multicast, called MChord, is proposed, which uses multicast technology to obtain physical neighbor information for routing. Simulation shows that it can shorten network search delay greatly, reduce routing hops effectively and improve the routing performance.
