Abstract: Setting whales as network nodes, the QoS routing problem was researched for the particular environment of underwater acoustic DTN. For the constraints of energy and bandwidth, a novel QoS routing algorithm based on nodes' mobility model was proposed. Through theoretical analysis and simulations, the aspects of packet lost rate, energy consumption and latency of the algorithm achieve the prospective design objects. The work of this literature has important significance on protection of endangered whales, the oceans and seas observation, resources exploration and so on.

Key words: Delay and disruption tolerant network, QoS routing, Mobility model
