Abstract: A hierarchical service discovery system and a method thereof are provided to enable a discovery agent to collect services existing in each domain by mutually interworking with heterogeneous service discovery protocols, so that a user of an agent platform can use the collected services. An LSD(Lightweight Service Discovery)(103) is designed as a lightweight service discovery protocol appropriate for an ad hoc environment having limited resources. The LSD(103) generates a discovery agent on an agent platform suited to the ad hoc environment. The discovery agent receives a service registration message sent from a UPnP(Universal Plug and Play) protocol to store the received message within the agent platform, so that another agent can use the message. A user agent of the agent platform is able to search an ad hoc network, a home network, and even an Internet range through a one-time searching function.
