The Price of Validity in Dynamic Networks
Massive-scale self-administered networks like Peer-to-Peer and Sensor Networks have data distributed across thousands of participant hosts. These networks are highly dynamic with ...

Cache placement in sensor networks under an update cost constraint
In this paper, we address an optimization problem that arises in the context of cache placement in sensor networks. In particular, we consider the cache placement problem where th...

Opportunistic Processing and Query of Motion Trajectories in Wireless Sensor Networks
—We study the problem of in-network processing and queries of trajectories of moving targets in a sensor network. The main idea is to exploit the spatial coherence of target traj...
