Impact of multi-query optimization in sensor networks
In this paper, we study the problem of processing multiple queries in a wireless sensor network. We focus on multiquery optimization at the base station level to minimize the numb...

Query Evaluation in Peer-to-Peer Networks of Taxonomy-Based Sources
We consider the problem of query evaluation in Peer-to-Peer (P2P) systems that support semantic-based retrieval services. We confine ourselves to the case where the peers employ t...

SAQA: Spatial and Attribute Based Query Aggregation in Wireless Sensor Networks
In most wireless sensor networks, applications submit their requests as queries and wireless sensor network transmits the requested data to the applications. However, most existing...

Query privacy in wireless sensor networks
— Existing mechanisms for querying wireless sensor networks leak client interests to the servers performing the queries. The leaks are not only in terms of specific regions but ...

Two-Tier Multiple Query Optimization for Sensor Networks
When there are multiple queries posed to the resourceconstrained wireless sensor network, it is critical to process them efficiently. In this paper, we propose a Two-Tier Multipl...
