学 号： 指 and then study its various functions can be achieved, at home and abroad in their various fields such as networking research status, through the analysis, the analysis of the process of selection research direction, Finally, choose the positioning algorithms to get a breakthrough, and then a follow-up study to expand the content. Secondly introduces the basic concepts of wireless sensors to analyze the composition of each basic unit in the network among its main function, and location algorithm in its category, we introduce three classical algorithm theory, and also with non-Ranging algorithm comparison algorithm derived non-ranging superiority, analysis and research three applications currently available algorithms, and finally sorted out the algorithm method.
By Chan for the TDOA algorithm, TDOA positioning method of least squares algorithm and weighted least squares method TDOA location algorithm to conduct a study to improve the accuracy in accordance with the idea, culminating in three algorithms based on an optimization algorithm that attempts to carry out centroid processing algorithm . Then use simulation software matlab software networking and simulation, and ultimately through matlab simulation and verification successfully. Then a large number of experimental data proved that through the centroid weighting process TDOA algorithm can be applied in practice.
Keywords: wireless sensor networks, chan algorithm, TDOA, weighted centroid, time delay
