Public Key Infrastructure (PKI) are offering a technical solution for efficient revocation in PKI based key distribution schemes. Researches revealed that PKI trust and revocation based operations may not be effective for large scale dynamic network which can engender bottlenecking, overhead and undesirable centralization. Identity-Based Encryption (IBE) has figured as secure and efficient public...
For the problem of low accuracy using K-means clustering algorithm to segment noisy brain magnetic resonance imaging (MRI) images, this paper proposed a strategy to improve segmentation accuracy. Firstly, the strategy uses wavelet transform to brain MRI image denoising, secondly, brain MRI image is segmented by k-means clustering algorithm. Experimental results show that the proposed strategy can...
Many applications of mobile ad hoc networks (MANETs) adopt hierarchical structure for the scalability and simplify of management. Clustering is the most popular method to impose a hierarchical structure in MANETs. As a newly- proposed weighing-based clustering algorithm, the weighted clustering algorithm (WCA) has improved performance compared with other previous clustering algorithms. But the high...
