A clusterhead of a tree-based, mobile ad hoc network includes a mobile IP proxy resource for registering a received binding update request from a mobile ad hoc router within the network, creating a first mobile IP tunnel with the mobile ad hoc router, sending a second binding update request to a remote home agent of the mobile ad hoc router, and initiating a second mobile IP tunnel between the clusterhead and the home agent. If a packet received from the mobile ad hoc router specifies a destination determined as reachable within the mobile ad hoc network, use of the second mobile IP tunnel is minimized by outputting the packet toward the destination according to the mobile ad hoc routing protocol. If the packet is not reachable within the mobile ad hoc network, the packet is forwarded via the second mobile IP tunnel to ensure packet transmission is topologically correct.
