Top-k query evaluation in sensor networks under query response time constraint
Please cite this article in press as: W. Liang et a Sci. (2010), doi:10.1016/j.ins.2010.10.006 Top-k query in a wireless sensor network is to find the k sensor nodes with the highest sensing values. To evaluate the top-k query in such an energy-constrained network poses great challenges, due to the unique characteristics imposed on its sensors. Existing solutions for top-k query in the literatu...
متن کاملTop-k Query Evaluation in Sensor Networks with the Guaranteed Accuracy of Query Results
In many applications of sensor networks including environmental monitoring and surveillance, a large volume of sensed data generated by sensors needs to be either collected at the base station or aggregated within the network to respond to user queries. However, due to the unreliable wireless communication, robust query processing in such networks becomes a great challenge in the design of quer...
متن کاملTop-$k$ Query Result Completeness Verification in Tiered Sensor Networks
Storage nodes are expected to be placed as an intermediate tier of large scale sensor networks for caching the collected sensor readings and responding to queries with benefits of power and storage saving for ordinary sensors. Nevertheless, an important issue is that the compromised storage node may not only cause the privacy problem, but also return fake/incomplete query results. We propose a ...
متن کاملSecure Top-k Query Processing in Unattended Tiered Sensor Networks
Many future large-scale unattended sensor networks (USNs) are expected to follow a two-tier architecture with resource-poor sensor nodes at the lower tier and fewer resourcerich master nodes at the upper tier. Master nodes collect data from sensor nodes and then answer the queries from the network owner on their behalf. In hostile environments, master and sensor nodes may be compromised by the ...
