In this work, we propose a flooding-based routing protocol using network coding for underwater communications. Due to the high amount of duplicates that flooding-based protocols flood into the network, the sharing of information between the duplicates can improve the packet delivery ratio (PDR). Our simulations show that network coding increases the PDR, but a price is paid in terms of end-to-end delay and number of forwarded duplicates, with respect to other flooding-based protocols. In order to reduce the number of duplicates, while keeping the PDR and the end-to-end delay unchanged, we propose to upgrade the protocol with specific geographical information of the nodes.
