| Abstract(in English) | In sensor networks, time synchronization accuracy usually affects consistency in sensor data extracted from these systems. Therefore we have to select an appropriate time synchronization method with less power consumption of sensor nodes and adequate time synchronization accuracy to get consistent results. There exists a trade-off between a cost and capability of a sensor node when building such a sensor networks. In our study we have constructed sensor networks to extract human trajectories adopting time synchronization methods which are suitable for low-performance sensor nodes. And we introduce an evaluation criteria based upon continuity of trajectories for evaluating the time synchronization accuracy. |
