Network Mobility(NEMO)is needed to provide continuous network connectivity and movement transparency to nodes which moves together as a group, like in a moving vehicle. The protocol is currently being standarzed at IETF with a solution called NEMO Basic Support. However, the protocol lacks features for Route Optimization, which becomes a critical problem when a mobile network attaches behind another mobile network creating a form called Nested Mobile Networks. This paper addresss the problems of nested mobile networks, and propose Neighbor Route Discovery as its solution. From our experimental evaluation, we show the effects of nested mobile networks, and evaluate the effectiveness of our proposal through a prototype implementation.
