Multi-mobile-beacon assisted distributed node localization scheme

Abstract

To improve the localization precision and avoid scanning unknown nodes repeatedly in mobile beacon assisted localization method,a multi-mobile-beacon assisted localization scheme was proposed.The ons keep a certain relative position while traversing the network and ranging with TDoA,and provide information to unknown nodes to estimate locations.Two path planning methods based on optimal coverage strategy were introduced.Simulation resu that the proposed scheme and paths perform well.
