Although current service discovery protocols provide the same basic function of service discovery, they differ significantly in architecture, message exchange pattern, expected operating environment and service representation/description. These differences prevent service interoperability among protocols. In this paper, we propose service discovery mechanism, using CALM agent platform to guarantee scalability of scope of available services without modifying existing service discovery protocols. Agent technologies are rising as the key to the ubiquitous environment. Agents mean the software that automatically performs necessary tasks instead of users. And intelligent agents are the software that makes plans and implement them so that multi agents will be able to meet users' needs most effectively in cooperation with each other. Intelligent agents require a function that enables to find out users' tastes and apply them to the performance of tasks in order to provide the results in conformity with users' preferences. The proposed service discovery mechanism provides users with a wider selection of services, and convenient search methods. An advantage of the proposed architecture is that the user can obtain more suitable services than existing approaches about service discovery.
