Abstract:
1. A method for routing between Mobile Networks (MNs), each of the MNs including a Mobile Router (MR) connected to a backbone network via an access router for transmitting a data packet from a first MN to a second MN, the method comprising: broadcasting, by a first MR of the first MN, a first message including a flag indicating if an internal network prefix of a destination MN is included in the first message; receiving, by a second MR of the second MN, the first message; determining, by the second MR, if the internal network prefix is included in the first message based on the flag; comparing, by the second MR, the internal network prefix included in the first message with an internal network prefix of the second MR, when the internal network prefix is included in the first message; broadcasting, by the second MR, a second message including an internal network prefix of the first MN and the internal network prefix of the second MN, when the internal network prefix included in the first message corresponds to the internal network prefix of the second MR; receiving, by the first MR, the second message; and transmitting, by the first MR, the data packet using the internal network prefix of the second MR included in the second message, when the second message includes the internal network prefix of the destination MN.
