Abstract
How to position node in the wireless sensor network has been a popular research topic. Based on the research to the mobile node positioning, this paper proposes position estimation method based on support vector machine (SVM) and game theory. It firstly uses support vector machine to preliminary estimate the position of the mobile node, secondly, it conducts smooth treatment to nude estimation position though game theory. At last, through fisherman algorithm, it conducts treatment to estimation position and noise. From the mobile node localization effect, ranging error, anchor node distribution density and non-line-of-sight coefficient, simulation results illustrate that the algorithm of this paper can effectively improve the effective of node positioning.
