Abstract :
The paper deals with a synchronization scheme for ad hoc network. The proposal is a distributed synchronization algorithm based on the convergence of nodes clock parameters to a mean reference using a diffusion method. The protocol measures time of arrival (TOA) of localization techniques using pulsed UWB modulation to estimate the delays and drifts values.
