Abstract
The range-free node localization techniques are attractive in wireless sensor networks. However, only based on the connectivity information, the range-free schemes are usually not accurate. The transmission radio power of the sensor nodes is often adjustable and multiple levels of the transmission power correspond to multiple levels of the communication radius. Thus an improved range-free node localization algorithm inspired by multiscale virtual forces is proposed, which adopts multiscale connectivity information. The simulation results showed that the proposed approach performs well in various scenario and the localization accuracy is improved.
