The node selection for the migration of a mobile agent depends on the content of the referenced metadata in the naming space. The reliability of the migrated information is determined by using the operation, cooperation, and metadata of individual agent in multi-agent system. In this paper, we propose the naming service of the multi-agent that supports more precise and efficient migration of the mobile agent and sensor network applications. For the service, we develop the naming agent and metatable to offer the information required for the mobile agent migration to the Server Push Agents as well as the Sensor Data Servers in the sensor network. The metatable consists of the reference object, name, URL, keyword and pointer to sink table. It also includes the add-on information related to sink node for sensor network application. In this paper, an algorithm for generating and updating metatable is suggested. The processes of the registration and retrieval of the metatable are presented ...
