Energy-efficient two-dimensional skyline query processing in wireless sensor networks

Alternative Tuples Based Probabilistic Skyline Query Processing in Wireless Sensor Networks

“…Networks. An extensive number of research works in this area have appeared in the literature [9][10][11][12][13][14][15][16]. Due to the limited energy budget available of sensor nodes, the primary issue is how to develop energy-efficient techniques to reduce communication and energy costs in the networks.…”

“…EMSE utilizes both global and local optimization mechanisms to eliminate unnecessary data transmission. In literature [16], a new lter-based method, called SKYFILTER, was brought up for skyline query processing. The method provides an enhanced efficiency by reduction of the total wireless communication between sensor nodes.…”

“…As one of the most important means, multiobjective decision, skyline query [4][5][6][7][8] processing technologies have brought a large number of excellent researches, both in WSNs [9][10][11][12][13][14][15][16] and for uncertain data [17][18][19][20][21][22][23][24][25][26]. Considering a wireless sensor network that consists of a large amount of sensor nodes deployed in a geographical region, sensing data are collected by these distributed sensor nodes.…”

“…Accordingly, there could be multiple sensor nodes deployed in certain zones to promote the precision of uncertain data. As a result, many queries in WSNs that rarely need transmitting every piece of sensing data in the local sensor nodes have been well studied to reduce the communication cost and to speed up the computation [9][10][11][12][13][14][15][16], for instance, sliding window skylines in sensor network [11,12], continuous skyline monitoring in WSNs [10], probabilistic query of uncertain data streams [18,19], dynamic (or relative) skylines [25], and distributed uncertain skyline query [26]. Nevertheless, most of these researches are studied under a centralized system setting.…”

Enhanced Distributed Dynamic Skyline Query for Wireless Sensor Networks

“…Various types of query techniques have been developed over WSNs including min-max [1], top-k [2,3] and skyline [4]. Skyline and its variants such as traditional skyline [5] and dynamic skyline [6][7][8] have been applied in many multiple criteria decision making applications.…”
