On the joint synchronization of clock offset and Skew in RBS-protocol Academic Article

abstract

• Motivated by the necessity of having a good clock synchronization amongst the nodes of wireless ad-hoc sensor networks, the joint maximum likelihood (JML) estimator for clock phase offset and skew under exponential noise model for reference broadcast synchronization (RBS) protocol is formulated and found via a direct algorithm. The Gibbs Sampler is also proposed for joint clock phase offset and skew estimation and shown to provide superior performance relative to JMLestimator. Lower and upper bounds for the mean-square errors (MSE) of JML-estimator and Gibbs Sampler are introduced in terms of the MSE of the Uniform Minimum Variance Unbiased (UMVU) estimator and the conventional Best Linear Unbiased Estimator (BLUE), respectively. 2008 IEEE.
