Abstract: Wireless sensor networks (WSNs) play a central role in the Internet of Things (IoT). It consists of small-size sensor nodes connected to the internet through gateways providing content rich information. So, the traffic transmission between sensor nodes over radio links requires highly bandwidth and needs to ensure the reliability of the data. Therefore, providing safe communications of sensor data over wireless communication channel plays an essential role. Thus, the important issue on wireless sensor networks is to find an optimal schema that ensuring energy efficiency together with the security. In contrast, implementing traditional cryptographic algorithms is not very well suited for WSNs nodes. In this article, a novel combination of spread spectrum into watermarking scheme is presented. This watermarking schema based on direct-frequency-time spread spectrum secures data communication against jamming and falsification to ensure data integrity and increases resistance to interference at the same time ensures the energy efficiency.
