Aggregate query processing in the presence of duplicates

In addition, when the sensing areas of sensor nodes are disjoint, the coordinator of each sensor becomes itself and we perform traditional aggregate query processing Thus, the problem we are considering is a generalization of the traditional in-network aggregation problemAggregate Query Processing in Ad-Hoc Sensor Networks ,Download Presentation Aggregate Query Processing in Ad-Hoc Sensor Networks An Image/Link below is provided (as is) to download presentation Download Policy: Content on the Website is provided to you AS IS for your information and personal use and may not be sold / licensed / shared on other websites without getting consent from its authorRobust and Efficient Aggregate Query Processing in ,Robust and Efficient Aggregate Query Processing in Wireless Sensor Networks Kebin Liu & Lei Chen & Yunhao Liu & Minglu Li Published online: 8 May 2008

REQUEST: Region-Based Query Processing in Sensor Networks

Only a few approaches proposed the processing of grouped aggregate queries However, since groups in their approaches are disjoint, some relevant regions to the query can be missing In this paper, we propose REQUEST, region-based query processing in sensor networks A region in our approach is defined as a maximal set of nodes located within a circle having a diameter specified in the query Complex query processing in wireless sensor networks ,Daniel, TE, Newman, RM, Gaura, E & Mount, SNI 2007, Complex query processing in wireless sensor networks in PM2HW2N '07 Proceedings of the 2nd ACM workshop on Performance monitoring and measurement of heterogeneous wireless and wired networksPoster Abstract: Energy›Efcient Data Organization and ,Recent sensor networks research has produced a class of data stor- range-aggregate query processing within our system Our system compiles an SQL query at the query issuer and con-structs an efcient query plan that includes an optimal join order using only locally available information in the form of a histogram We argue that it is important to choose a good join order during query
