Abstract: It is significant and meaningful for scienctific research and transportation security to monitor the track and roadbedod rail and to transmit the corresponding information to the locomotive manipulator. In this paper, we present a novel wireless sensor network with a multi-sink mobility model for track and roadbed monitoring using wireless sensor networks with sink mobility. We have recommended the network’s structure and defined the hierarchy of the data transmission. A dynamic Power-Control scheme is also proposed. Simulation results show that this model is useful and effective.

Key words: wireless sensor networks, sink mobility, dynamic power-control
