Abstract. For ubiquitous communication self-organising adhoc networks become more and more important. We consider mobile phones as appropriate secure gateways to provide access to ...
We present lower bounds on the space required to estimate the quantiles of a stream of numerical values. Quantile estimation is perhaps the most studied problem in the data stream ...
—In this paper, we introduce an objective model of trust in peer-to-peer networks. Based on this model, we develop protocols that can be used by the peers in a peer-to-peer netwo...
