Abstract：
 The invention features: less energy expenses, less complexity, and compensation function for the drift and offset. It uses PLL (phase locked loop) principal and a single-way broadcast synchronous mechanism to scheme out a solution which simultaneously has the compensation function for the drift and offset and the time synchronization function of radio sensor network.
