The development of the micro-manufacturing technology, communication technology and the battery technology in recent years leads to that the sensor has the abilities of sensing, wireless communication and data processing, and that it can be Lacoste Polo manufactured with a low price. The sensor is therefore being widely used in many practical applications, including military and defense, environmental monitoring, traffic management, health care, manufacturing business and anti-terrorism domain. The wireless sensor network (WSN) is often large-scale and the chi dazzle computational and storage capabilities and energy resource of its nodes are fairly limited. Moreover, there are ralph lauren polo shirts potential safety hazards in WSN. As a result, these arouse strong research interests of many research scholars, and many new methods, which aim to ensure the security of WSN, have been discount wedding dresses proposed.This paper is focused on the security-related problems in WSN and proposes digital watermarking-based methods to address these problems. The main contributions of this paper are as custom made prom dresses follows.1) Based on the proposed network model, this paper designs and implements a data transmission platform for WSN, which contains the five components, namely, node pre-distribution, data processing, routing, data checking and data analysis. By modifying the relevant parameters in the network system, any network topology will be generated. Similarly, by modifying the data routing methods, different transmission methods will be used to transmit the WSN data.
