Localization of sensor nodes in WSN in many different scenarios is becoming an important issue due to their widespread application. Different system parameters are changed in order to have a better performance. In this study are taken in consideration the simulation of the approaches of Hybrid algorithm but now with two more improvements brought to it. Based on simulations we understood the influence of dimensioning, so from 1D to 3D the localization efficiency will increase because at the 3D the reference nodes will interact in more directions, but also the convergence time will increase because of the network complexity. The aim is to reach a better time of network convergence, cluster's node localization, and a successful rate of localization.
