An Energy-Efficient Query Aggregation Scheme for Wireless Sensor Networks
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) ...

Handling dynamics in gossip-based aggregation schemes
A problem in large and dynamic networks consists in making available at each node global information about the state of the network. Gossip-based aggregation schemes are a simple ...

Flows in dynamic networks with aggregate arc capacities
Dynamic networks are characterized by transit times on edges. Dynamic flow problems consider transshipment problems in dynamic networks. We introduce a new version of dynamic fl...

Hierarchical In-Network Data Aggregation with Quality Guarantees
Earlier work has demonstrated the effectiveness of in-network data aggregation in order to minimize the amount of messages exchanged during continuous queries in large sensor netwo...

Self-organized aggregation in irregular wireless networks
Gossip-based epidemic protocols are used to aggregate data in distributed systems. This fault-tolerant approach does neither require maintenance of any global network state nor kno...
