Node localization is the foundation of the wireless sensor *** traditional DVHop localization algorithm has been studied in this *** order to solve the problem of DV-Hop localization algorithm,an improved DV-Hop localization algorithm has been proposed. Which uses correction value reducing the measurement average hop distance error and selecting optimal anchor nodes by APIT *** simulation results demonstrate that,the improved localization algorithm(DV-SCA)has a better localization accuracy than the original DV-Hop algorithm.

Previously there was algorithm shortage about making watermark hidden in semantic meaning of text and text formatting, this paper presents a new zero-watermark algorithm based on English text and the algorithm is suitable for Chinese text as well. Firstly, the algorithm determines the textual characteristics through the punctuation mark of texts. Then add the watermark information into the host through coring the information between cryptographic watermark and textual characteristics. The algorithm has a good concealment and strong robustness.
