Abstract
In conventional network environments, routing implies a stable world in which the vision of a next hop is consistent with the vision a forwarding node, so that a packet can progress, for example, in a greedy fashion that reduces a remaining cost at each hop, to a destination. However, in the world of mobile delay tolerant networking (DTN), nodes can move in any direction, nodes may forward packets when they meet a peer, and may move in between such actions. Thus, the relative position of nodes can change between meeting such that it can become difficult to compute a physical path based on a position of all nodes. Techniques presented herein propose a foundational "routing to the future" model for mobile DTN nodes that may enable predictable rendezvous among such nodes. During operation, a router can, for example, compute a route along rendezvous points while optimizing for the total latency, energy, and chances of delivery based on the probability of the rendezvous to effectively occur.
