The metatable of naming agent for the naming service of sensor network

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 metatable and its management method that supports more precise and efficient migration of the mobile agent and sensor network applications. For the service, we develop the metatable consists of the reference object, name, URL, keyword and pointer to sink table. It also includes the add-on information related to the sink node (i.e. sink number, sink information and sink URL) for the sensor network application. Furthermore, we suggest the algorithms for generating and updating the metatable and acquiring the server list for the migration. The results of experiments are compared with non-applied metadata to guarantee the reliability of our approach.
