Mobile network is frequently faced with link disconnection problem. In such cases, mobile router in the network takes a role of an access point to the infrastructure. Thus, a mobile router must have both a routing protocol for the moving network itself and a mechanism to communicate with the infrastructure. Even when the mobile network is moving, while changing its point of attachment to the infrastructure, the mobile router should continuously transmit packets to the nodes in the network. However, the existing tunneling protocol derived from IP-in-IP encapsulation of Mobile IPv4 to send packets to the nodes of the mobile network causes an additive delay and an IP header overhead. The delay and packet overhead deteriorate quality of real-time applications or streaming traffic like VoIP. In this paper, we propose a new tunneling protocol and a location registration method to minimize the effect of managing nested mobility. We compare performance of the proposed scheme with the legacy one. Our simulation results indicate that not only is the new scheme able to reduce the packet overhead, but also improve the QoS with respect of delay, link recovery time and packet delivery rate.
