In Delay and Disruption Tolerant Networking (DTN), Epidemic, PRoPHET and Spray and Wait protocols work by distributing one or more message copies (Bundles). They can naturally adapt to the mobile situation where the destination node moves from an old connection endpoint to a new connection endpoint. But they suffer from low delivery ratio because their routing decisions are based on the local knowledge given by the next hop node. They also incur long latencies because Bundle copies are not immediately forwarded until any suitable condition for forwarding is met. To solve these problems, we propose a Handoff-based Deterministic Routing Protocol (HDRP) where the handoff mechanism includes the registration of locations by mobile nodes and backward propagation and caching of these locations at each of the routers in the experienced route. Our simulation results indicate that HDRP outperforms other existing protocols in terms of end-to-end latency as well as delivery ratio for different network scenarios.
