A Three-Phase Top- Query Based Distributed Data Collection Scheme in Wireless Sensor Networks
International Journal of Distributed Sensor Networks, 2015 We propose a three-phase top- k query based distributed data collection scheme which is designed for clustered or multisink wireless sensor networks. The proposed scheme consists of a distributed iterative hard thresholding algorithm and a three-phase ...

I/O-Efficient Planar Range Skyline and Attrition Priority Queues [PDF]
, 2013 In the planar range skyline reporting problem, we store a set P of n 2D points in a structure such that, given a query rectangle Q = [a_1, a_2] x [b_1, b_2], the maxima (a.k.a. skyline) of P \cap Q can be reported efficiently.

Efficient top-k string similarity query algorithms
Tongxin xuebao, 2014 Computing top-k similar strings based on edit distance,i.e.,given a query string σ and string set S,finding k similar strings to σ based on edit distance from S.Firstly,two adaptive filter strategies based on length-skip index are proposed,such that to ...

Top-k Query Processing and Malicious Node Identification Based on Node Grouping in MANETs
IEEE Access, 2016 In mobile ad hoc networks (MANETs), it is effective to retrieve data items using top-k query. However, accurate results may not be acquired in environments when malicious nodes are present. In this paper, we assume that malicious nodes attempt to replace

Range Queries on Uncertain Data
, 2015 Given a set $P$ of $n$ uncertain points on the real line, each represented by its one-dimensional probability density function, we consider the problem of building data structures on $P$ to answer range queries of the following three types for any query ...
