Through designing a quantum communication network, we propose a protocol for the teleportation between multiple senders and multiple receivers via only one controller. In order to rationally employ the quantum entanglement resources, the controller shares the entangled state with every sender, while there is no directly shared entanglement link between sender and receiver The security is analyzed in detail Moreover, this protocol reduces the classical communication cost in the public channel by means of the coding Crown Copyright (C) 2010 Published by Elsevier BV All rights reserved
