With rapid development of sensor networks technology, it becomes feasible to deploy multiple sensor networks in relevant area to collect interested information. Sensor nodes that are co-located but belong to different sensor networks may not be able to collaborate pro-perly to gain the capacity or performance. In this paper we propose a semantic-based sensor networks architecture that enables inter-networking of sensor networks. In this Semantic Sensor Net (SSN), a semantic tag is attached to the sensory data so that the sensor networks are able to exchange information and work collaboratively. The process of semantic creation and maintenance is described. We also introduce the concept of InterSensorNet. This infra-structure enables efficient information exchange and information extraction among multiple sensor networks. Key words: semantics, wireless sensor networks, InterSensorNet
