Pervasive reconfigurable sensor network instrument

In order to design a hardware platform structure of sensor network instrument to get information for pervasive computing, combining mobile computing and instrument with modem electronic design automation (EDA), one pervasive sensor network instrument structure with wireless communication and network was put forward, which was reconfigurable in system. The instrument was equipped with structure of embedded system, in system programming (ISP) device and multiple sensors, and was linked to pico-cell network or Internet by mobile digital network. The ISP technology and intellectual property (IP) technology were applied to the instrument so as to upgrade hardware in system without changing instrument hardware structure and upgrade function only by changing embedded soft. The pervasive sensor network computing was used in the instrument of science and technology. The instrument has characteristics of reconfiguration in system with wireless mobile and Internet. The structure of the pervasive instrument, wireless communication technology and process of reconfiguration in system were afforded in this paper. The example about image communication based on the instrument structure is introduced. The application indicates that the reconfigurable pervasive sensor network instrument is applicable and suitable for pervasive computing.
