Network Coordinate (NC) systems provide a lightweight and useful way for scalable Internet distance prediction while serving as an important component in many Peer-to-Peer applications. Most of the existing NC systems utilize the Euclidean distance model, which is largely impaired by the persistent occurrence of Triangle Inequality Violation (TIV) in the Internet. Recently, matrix factorization (MF)...
The network proximity metrics, such as bottleneck bandwidth and round-trip time, are very useful in different network applications. The round-trip-time prediction has been studied extensively. However, the prediction of bottleneck bandwidth has received much less attention. Therefore, we attempt to design a new bottleneck bandwidth prediction system by matrix factorization. As a first step, we focus...
Caching can improve the browser's efficiency, this paper proposes one distributed sharing model of the browser cache: each end-host's address and the Web site URL address are mapped to the identical key space, the storing information of the shared cache mapped to key k is saved on the same key k mapped end-host; it also presents a distributed lookup protocol with a constant O(1) hop per lookup request,...
Nowadays, the security of Web pages becomes very important. Zhao and Lu had proposed a PCA-based watermarking scheme for Web pages; their scheme is an effective tool for tamper-proof of Web pages. However, the PCA algorithm is time-consuming, especially when the size of Web page is too large. In this paper, we proposed two novel fragile Web page watermarking schemes, in which simple principal component...
Nowadays, the security of Web pages becomes very important. Zhao and Lu had proposed a PCA-based watermarking scheme for Web pages; their scheme is an effective tool for tamper-proof of Web pages. However, the PCA algorithm is time-consuming, especially when the size of Web page is too large. Chia-Chi Wu et al. proposed a Web page watermarking scheme base on hash functions, claiming that their scheme...
