A Key Pre-distribution Scheme Based on Deployment Information
Shulan Xia,Jilin Wang,Ru-gang Wang 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.11
A scheme of grouping key distribution based on polynomial protocol is proposed and experimentally demonstrated. The grouping idea is ingeniously used in the design of key distribution. The performance is experimental demonstrated by comparing with kinds of random key pre-distribution schemes. The results show that it can not only guarantee the key connected rate but also strengthen the security performance of the network, and this scheme is very suitable for static underwater acoustic communications network.
An Improved Algorithm of Speech Emotion Recognition
Shulan Xia,Jilin Wang,Ru-gang Wang,Li Zhao 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.12
The traditional K-nearest neighbor algorithm existences of the risk of miscarriage of justice, for its shortage a speech emotion recognition algorithm based on fuzzy K-nearest neighbors is proposed. By introducing the fuzzy membership concept, different characteristic parameters for the different contribution of emotion recognition are calculated, and the weighted Euclidean distance is used in speech emotion recognition. The experimental results show the effectiveness of the algorithm.
