Abstract: Anycasting provides a means to locate and communicate with the "best" server in a group of servers which have the same anycast address. The characteristics of anycast routing techniques at the network layer are discussed,and the advantages of anycast are analyzed on mobile network.An anycast routing algorithm based on on-demand idea for Ad Hoc network is proposed.
