HYMAD: Hybrid DTN-MANET Routing for Dense and Highly Dynamic Wireless Networks

Understand

In this paper we propose HYMAD, a Hybrid DTN-MANET routing protocol which uses DTN between disjoint groups of nodes while using MANET routing within these groups.

• HYMAD is fully decentralized and only makes use of topological information exchanges between the nodes.
• We evaluate the scheme in simulation by replaying real life traces which exhibit this highly dynamic connectivity.
• The results show that HYMAD outperforms the multi-copy Spray-and-Wait DTN routing protocol it extends, both in terms of delivery ratio and delay, for any number of message copies.
