Abstract
In order to make node self-localization precision satisfy the need of varied network size
hybrid-hop Monte-Carlo method is proposed to solve the constraint of low anchor node density.Multi-hop anchor node method is utilized to collect anchor nodes information in condition of various anchor node density
and then to calculate the position of node with different sampling method.The simulation results show that the method can improve the accuracy of node localization.This method is self-adaptive and practical.
