—Today, many network applications require shorter react time. Robotic field is an excellent example of these needs: robot react time has a direct effect on its task’s complexit...
This paper presents a novel method for optimizing sliding window based continuous queries. We deal with two categories of aggregation operations: stepwise aggregation (e.g. COUNT) ...
According to the application domain, Wireless Sensor Networks (WSNs) differ in a number of ways (e. g., deployment strategy, node mobility, available resources, node heterogeneity...
Energy in sensor networks is a distributed, non-transferable resource. Over time, differences in energy availability are likely to arise. Protocols like routing trees may concent...
