Service Discovery System based on P2P in Underwater IoT Device and the Underwater IoT Device thereof

摘要

The present invention relates to a P2P-based service discovery method in an underwater IoT device, and the underwater IoT device to search and access various application services provided on different kinds of networks on the basis of P2P in an IoT communication device. The underwater IoT device using the P2P-based service discovery method according to the present invention comprises: an underwater IoT protocol unit which performs communication with a ground IoT device or another underwater IoT device by using ground or underground communication protocol; a service discovery function nit which communicates with the underwater IoT protocol unit, forms a P2P overlay network for performing service discovery, performs service searching in response to a service searching request, and provides a service searching resu and an intersection layer interface unit which processes an interface for communication between the underwater IoT protocol unit and the service discovery function unit.
