Optimizing data replication for expanding ring-based queries in wireless sensor networks
We consider the problem of optimizing the number of replicas for event information in wireless sensor networks, when queries are disseminated using expanding rings. We obtain clos...

Supporting Aggregate Queries Over Ad-Hoc Wireless Sensor Networks
We show how the database community’s notion of a generic query interface for data aggregation can be applied to ad-hoc networks of sensor devices. As has been noted in the senso...

Operator Placement for Snapshot Multi-predicate Queries in Wireless Sensor Networks
— This work aims at minimize the cost of answering snapshot multi-predicate queries in high-communication-cost networks. High-communication-cost (HCC) networks is a family of net...

Constraint-Based Distance Estimation in Ad-Hoc Wireless Sensor Networks
Abstract. We propose a lightweight localisation approach for supporting distance and range queries in ad hoc wireless sensor networks. In contrast to most previous localisation app...
