ABSTRACT:
A recording medium including computer program instructions which cause a computer to execute a method of assigning IP addresses to mobile IP nodes in heterogeneous networks in which a home agent dynamically assigns a temporary IP care-of address to a static IP home address when the mobile node is moved in the heterogeneous networks, the dynamic care-of address indicating the topologically current network location of the mobile node and IP data packets having the IP home address of the mobile node as a destination address being redirected to the care-of address of the mobile node, including checking the mobile node for available physical network interfaces, generating a lookup table with the available and configurable physical network interfaces, linking to one of the available physical network interfaces, accessing the heterogeneous networks via a permanent virtual IP network interface generated in the mobile node, the generated permanent virtual IP network interface being linked to the current network, and including a generated virtual L3 layer and a generated virtual L2 layer and updating, during a change of the physical network interface of the mobile node, the link of the permanent virtual IP network interface to the network based on the lookup table.
