Abstract: PURPOSE: A communication method and system using a global ID for internet of things (IoT) are provided to perform seamless communication regardless of protocol difference or the existence of an Internet protocol (IP) between objects arranged on a plurality of different lower networks. CONSTITUTION: IoT (200) comprises at least one object (SN), at least one thing's profile service (TPS) server (TPS), at least one thing's identification service (TIDS) server (TIDS), at least one domain name service (DNS) server (DNS), at least one dynamic domain name service (DDNS) server (DDNS), and at least one thing's application level protocol (TALP) adapter (TALPA). The object is allocated with a global ID, a domain name, and an IP address. The TPS server maps and stores a profile including a global ID for each object, a type of service which the object supports, and protocol information which the object uses. The TIDS server maps and stores the global ID and domain name of the object and the IP address of the TPS server. The DNS server matches and stores the domain name and IP address of the object. The TALP adapter converts a protocol into a TALP, application layer protocol, and transmits the TALP so that an object included in a lower network (210-230) can communicate with the other object regardless of a type of the lower network.
