Previously, we proposed the Directional Flooding-based Routing (DFR) protocol where the flooding area is updated according to link quality to provide reliable packet transmissions in loss-prone underwater wireless sensor networks (UWSNs). However, since the original DFR was designed to have static system parameters to consider a QoS requirement, it cannot meet the QoS requirement if the network condition changes dynamically which is inherent in UWSNs. We therefore propose two enhanced versions of DFR which control the number of forwarding nodes through an entire or partial path, based on feedback information from the sink. |
