Wireless Sensor Networks should be self-organized to enhance the coverage after an initial random deployment. Virtual Forces Algorithm, VFA, is one of the most efficient algorithms proposed in the literature. Simulation results prove that the use of this algorithm does not achieve full coverage and connectivity in some cases, even when the number of sensors is sufficient. Because of that, our contribution is to propose some improvement to ensure coverage, connectivity and fault-tolerance, while saving energy. Our final proposed version Dth_Lmax_Serialized_VFA achieves the performance criteria previously cited by serializing and limiting nodes moves as well as increasing the robustness degree.
