Abstract
Aiming at localization problem of WSNs
a new signal bit switching scheme is proposed to locate unknown nodes
which combines mobile beacon and DV-Hop algorithm
on the premise that Scan mobile mode is adopted.The algorithm is simple and is easy to realize
and can perfectly achieve localization effect in a short time.Simulation results prove that the algorithm effectively reduces localization cost and improves localization precision.
