Sensor networks are dense wired or wireless networks for collecting and disseminating environmental data. They have some limited like energy that usually provide by battery and storages in order that we cannot save any generated data. The most energy consumer of energy is transmitting. Sensor networks generate immense amount of data. They sends collected data somewhere for storing to response users queries. In this paper we describe a new sensor data storage we called SHD, arrange sensors in hierarchical form that shows data in semantic model
