Coverage optimization algorithm based on VF-CS in mobile sensor network
Published 2018-03-01“…A random placement of large-scale sensor network in the outdoor environment often causes low coverage.An area coverage optimization algorithm of mobile sensor network (MSN) based on virtual force perturbation and Cuckoo search (VF-CS) was proposed.Firstly,the virtual force of the sensor nodes within the Thiessen polygon was analyzed based on the partitioning of Voronoi diagram of the monitoring area.Secondly,the force of polygon vertices and neighbor nodes was taken as the perturbation factor for updating the node’s location of the Cuckoo search (CS).Finally,the VF-CS guided the node to move so as to achieve the optimal coverage.The simulation results demonstrate that the proposed algorithm has higher coverage and shorter average moving distance of nodes than the Voronoi diagram based algorithms in literatures.…”

Energy-efficient sampling and transmission scheme in wireless multimedia sensor networks
Published 2011-01-01“…An energy-efficient data sampling and transmission method in wireless multimedia sensor networks was proposed.Node’s sensing direction could be adjusted with the help of Voronoi diagram which enhances network coverage level.And energy consumption on sampling was reduced on the basis of periodical sleeping as well as different sampling granularities.Moreover,the transmission overhead was further brought down by means of color block matching.Simulation results show that this method obtains satisfactory performance on prolonging networks lifetime.…”

Spatio-temporal aware privacy-preserving scheme in LBS
Published 2018-05-01“…Location-based service (LBS) brings a lot of conveniences in people’s daily life,but the conveniences are accompanied with the leaking of privacy.A dummy-based location-preserving scheme was proposed,which took the correlation between spatial issues and temporal issues into account.Two algorithms were included in this scheme,map dividing algorithm and dummy contents determining algorithm.The map dividing algorithm divided the map into discrete location cells by Voronoi Diagram to ensure these discrete location cells were not adjacent to each other.The dummy contents determining algorithm replaced the query content in previous moment by the intending location in next moment,which efficiently avoided the adversary inferring mobile users’ sensitive information according to the correlation between spatial issues and temporal issues.The simulation experiments show that the proposed scheme is effective and efficient.…”

A novel minimal exposure path problem in wireless sensor networks and its solution algorithm
Published 2016-08-01“…In this situation, because a corresponding weighted graph model cannot be developed, the methods that are used to solve the original minimal exposure path problem (the grid method and the Voronoi diagram method) are ineffective. Thus, this article first converts the problem into an optimization problem with constraint conditions. …”
