Fully Distributed Localization Model and Optimized Algorithm For Large-Scale Wireless Sensor Network

摘要

Aiming at the inherent deficiencies of large-scale wireless sensor network for distributed positioning algorithm,the DV-hop algorithm is mainly studied and improved,and two kinds of improved algorithms DV-hop and DV-hop+Lastdist DV-hop-MinMax are proposed.The DV-hop+Lastdist improves the positioning accuracy of the node by only adding a message variable,while the DV-hop-MinMax effectively reduces the costs of floating-point operations and power consumption,and can select the appropriate algorithm according to actual application environment.Finally,the paper gives the method to realize OMNeT + + in the simulation environment,and carries out the simulation analysis.
