Sensor Node Easy Moving Monitoring Region Location Algorithm in Internet of Things
Abstract: Because of the
influence from geographical location, weather and other kinds of circumstances
in monitored areas, the shift of the node location and non-uniform
distribution, this paper proposed animproved DV-Hop location algorithm. First
of all, the package structure by changing the anchor nodes toreduce the number
of hops data acquisition phase node data storage; introducing weights to the
average hop distance calculation phase the original average hop distance
calculation method was improved, andbetween the node and anchor node distance
calculated on the basis of reference anchor nodes aredifferent; then, iterative
refinement of node localization stage through the use of multilateral
measurement method and Taylor series. Finally, simulation experiment of this
method, and compared with the existing methods, the results prove that the
method in this paper can greatly reduce positioning errors withoutadding
hardware equipment and network traffic, improve the positioning accuracy, a
better solution to the problem of node localization networking monitoring area.
