Chord routing algorithm based on limited multicasting

Chord is a successful routing algorithm,but the inconsistence between logistic routing and physical routing leads to a very big network delay if the node routing only relies on logistic distance and this will seriously affect the routing efficiency.A Chord routing algorithm based on limited network layer multicasting was proposed,which used multicast technology to obtain physical neighbor nodes and improved on original Chord routing algorithm.It can shorten network search delay greatly,reduce routing hops effectively and improve the performance of routing.
