| Abstract: | Wireless sensor networks is a new and widely applied approach for information acquisition and processing. We can employ it to implement large-scale surveillance and tracking. Node localization is one of its key technologies.The accuracy of node localization directly influences the backward information transmission and surveillance. We employ BP neural network to optimize the location and to verify the measurement results. Results show that the algorithm improves the positioning accuracy. |
| Keywords: | wireless sensor networks node localization BP algorithm positioning accuracy |
