Today, marine data acquisition and cartography systems can achieve low-cost data acquisition and processing by composing IoT, mobile ad hoc network (MANET), and delay-tolerant networking (DTN) technologies. Specifically, sea vessels, which equip multiple sensors, can utilize International Telecommunication Union (ITU) standards-based very high frequency (VHF) data exchange system to route the sensory data to the gateway node (i.e. cellular base station) at the shore via the ship-based MANET. Afterwards, the gateway can relay the data to the central cloud. In general, such an architecture may produce many duplicated sensory transmission readings due to the redundant data transmitted from different ships. In order to remove such duplication and to improve the efficiency, the system can deploy fog computing service at the gateway nodes to preprocess the sensory data toward preventing the gateways sending duplicated data to the central server [4].
