Each mobile router in an ad hoc mobile network is configured for concurrently attaching to multiple parents advertising respective parent metrics relative to a prescribed destination of the ad hoc mobile network. The mobile router selects an advertised metrics relative to the prescribed destination based on adding a prescribed increment to a maximum one of the parent metrics, enabling the mobile routers to form a directed acyclic graph relative to the prescribed destination. Each mobile router sends to each of its parents a neighbor advertisement message specifying at least one reachable prefix, a corresponding cost for reaching the reachable prefix, and a corresponding sequence identifier that enables the parents to validate the neighbor advertisement message relative to stored router entries. Hence, mobile routers automatically can form a directed acylic graph relative to the prescribed destination, and can distribute routing information with minimal overhead. |
