Brief Announcement: Universal Data Aggregation Trees for Sensor Networks in Low Doubling Metrics
Abstract. We describe a novel approach for constructing a single spanning tree for data aggregation towards a sink node. The tree is universal in the sense that it is static and in...

Secure hierarchical in-network aggregation in sensor networks
In-network aggregation is an essential primitive for performing queries on sensor network data. However, most aggregation algorithms assume that all intermediate nodes are trusted...

Coexistence of Various Topology Aggregation Methods in a Hierarchical Network
Quality of Service (QoS) routing methods are expected to replace existing routing protocols in future QoS-based data networks. QoS routing allows the selection of feasible paths f...

Exploiting duality in summarization with deterministic guarantees
Summarization is an important task in data mining. A major challenge over the past years has been the efficient construction of fixed-space synopses that provide a deterministic q...
