The Mobility First network architecture is introduced to differentiate the human readable names with corresponding Global Unique Identifiers (GUIDs), and the dynamic network address locators. The human readable name can be managed and assigned to a unique GUID by Name Certification Services (NCSs). GUIDs assigned to network objects (Things) are mapped to a set of network addresses (NAs). Delay and Disruption Tolerant Network (DTN) is used in the Mobility First for efficient communication. GUIDs are assigned to Internet of Things (IoT) and Internet of Underwater Things (IoUT). Underwater things can collect the underwater data using sensors, underwater modem, underwater Medium Access Control (MAC) board and transducer etc. Internet of Underwater Things (IoUT) can communicate the changes in the ocean environment to the offshore IoT. Underwater things are constructive in offshore investigation, disaster anticipation, data gathering, assisted navigation, pollution checking and strategic inspection. To achieve these features, this paper proposes architecture with three layers. They are IoUT layer, DTN communication layer and IoT layer. IoUT layer gathers the information with the help of underwater things. DTN communication layer sends this information to IoT layer with help of Global Name Resolution Service (GNRS). Dynamic binding of names to address is done by GNRS. By using IoT layer ocean data can be broadcasted in different applications like scientific applications, military applications, industrial applications and civilian applications. Results are shown by using the GUID accessing based on popularity.
