In delay tolerant network, a complete routing path from a source to a destination can not be guaranteed at most of the time. Therefore, traditional routing method for ad hoc network is not applicable in these situations. Current approaches for such networks are primarily based on redundant transmissions and single copy direct routing. However, they incur either high overhead due to excessive transmissions or long delays due to the incorrect path choices during forwarding. In this paper, we propose a direction based geographic routing scheme (DIG) for the intermittently connected network. Relying on the geographic location information, the packets are routed in a approximate ideal path to the destination, which significantly reduces the resource required in flooding-based algorithm and lead to decreased delay compared to the direct routing. Theoretical analyzes and simulations show that compared to the epidemic routing and direct routing, DIG provides nearly optimal delay with very low overhead.
