Abstract
In this paper, we proposed a time difference of arrival(TDOA) location method based on the semi-definite relaxation planning in order to achieve the accurate positioning of unknown nodes in sensor network. The unknown nodes include mobile nodes and target node. Based on measurement of time arrived, the noise has been considered, by relaxation the constraint conditions, the non-convex problem has been converted into a convex problem. Numerical simulation showed that the method can effectively improve the positioning precision of the unknown node.
