Wireless network sensor consists of small acceleration sensors connected to radio transmitter-receivers and a base unit connected to a PC with RS-232C (USB and Ethernet available). All of acceleration waveform data from sensors can be stored in a HDD of the PC. Each sensor works as an autonomous communication node and makes self-assembling into a network of sensors. Intermediate nodes assist distance nodes to reach the base station.
