Abstract—In hierarchical mobile ad hoc networks, the architectual stability is a key factor in determining the network performance. There are many solutions proposed to construct...
Abstract—We propose a strategy to perform query processing on P2P similarity search systems based on peers and superpeers. We show that by approximating global but resumed inform...
We present an approach to improving the precision of an initial document ranking wherein we utilize cluster information within a graph-based framework. The main idea is to perform...
