A localization algorithm from connectivity based on distributed weighted-multidimensional scaling (cdwMDS) algorithm is proposed in this paper. Each sensor selects a neighbor sensor adaptively, calculates the iteration step size with the average connectivity and updates the estimate location by optimizing the local cost function. Connectivity is used to determine the step size of gradient iterative optimization in this algorithm. After getting the estimated positions, a relative map is built and the absolute coordinates can be obtained. Simulation results show that this method could achieve higher localization accuracy and more stable convergence.
