Multiresolution Cube Estimators for Sensor Network Aggregate Queries
In this work we present in-network techniques to improve the efficiency of spatial aggregate queries. Such queries are very common in a sensornet setting, demanding more targeted t...

Secure Data Collection in Wireless Sensor Networks Using Randomized Dispersive Routes
—Compromised-node and denial-of-service are two key attacks in wireless sensor networks (WSNs). In this paper, we study routing mechanisms that circumvent (bypass) black holes fo...
