Abstract. A significant increase in real world event monitoring capability with wireless sensor networks brought a new challenge to ubiquitous computing. To manage high volume and...
We consider the problem of resource sharing when processing large numbers of continuous queries. We specifically address sliding-window aggregates over data streams, an important...
Efficient exploitation of the aggregate resources available to a researcher is a challenging and real problem. The challenge becomes all the greater when researchers who collaborat...
Continuous queries applied over nonterminating data streams usually specify windows in order to obtain an evolving –yet restricted– set of tuples and thus provide timely result...
When making an engineering design decision, it is often necessary to consider its implications on both system performance and dependability. In this paper, we present a performabi...
