摘要：

Since the data of wireless sensor networks play an important role in the communication, many strategies have been devised to protect the security of sensor networks. Due to the importance of copyright protection for valuable sensor data, we present a robust watermark algorithm as the solution in this paper. We make use of the numerical characteristic of sending time of the sensor packet to embed watermark. We compare the performance of three watermarking schemes, i.e., the method without key, the method with 8-bit key length, and with 16-bit key length, through conducting lots of simulation experiments. Simulation results show that our scheme can effectively protect the copyright of data while obtaining the tradeoff on computational cost.
