Abstract
According to the present invention, connection can be always maintained between the mobile node and the access router, and disruption of on-going transport session can be prevented by making effective use of two architectures (hierarchical and mesh architectures). The mobile nodes 1000-1, 1000-2 and 1000-3 are attached to the access router 1100-1. When the mobile node maintains link layer connectivity with the access router, it is in the hierarchical mode, whereas when the link layer connectivity is lost, it enters the mesh mode. In the mesh mode, the mobile node attempts to establish virtual link layer connectivity with the access router through other nodes by using mesh network protocol such as MANET. In the mesh mode, the packet is capsulated between the mobile node and the access router when the mobile node and the peer 1400-1 communicate with each other.
