  The DESERT Underwater framework (http://desert-underwater.dei.unipd.it/),
originally designed for simulating and testing underwater acoustic networks in
sea trials, has recently been extended to support real payload data
transmission through underwater multimodal networks. Specifically, the new
version of the framework is now able to transmit data in real time through the
EvoLogics S2C low-rate and high-rate acoustic modems, the SmartPORT low-cost
acoustic underwater modem prototype (AHOI) for IoT applications, as well as
Ethernet, surface WiFi, and the BlueComm optical modem. The system can also be
tested in the lab by employing a simulated channel, and the EvoLogics S2C DMAC
Emulator (DMACE)
