Claim:
A method for registering a mobile router (MR) in a multi-homing Network Mobility (NEMO) network system including multiple mobile routers, the method comprising the steps of: a) at a first MR, identifying a second MR that allows a peering relation to the first MR; b) at the first MR, transmitting a peer request message to the second MR for making a peer relation with the second MR; c) at the first MR, requesting a home agent (HA) of the first MR to authenticate the second MR in response to a peer request response from the second MR; d) at the HA, transmitting a peer mobile router registering request message to the second MR with a prefix of the first MR that transmitted the authentication request message to perform return routability (RR) authentication; and e) at the HA, notifying the authentication result of the second MR to the first MR when receiving a RR authentication result message including the prefix of the first MR to be registered as a peer from the second MR, where the RR authentication result message is a peer mobile router registering request response message.
