Abstract
In this paper, a new positioning algorithm is designed based on TDOA algorithm. The algorithm combines Trilateration Method and Multilateral Maximum Likelihood to achieve more optimized positioning effect. In this paper, the Trilateration Method, the Multilateral Maximum Likelihood, and the algorithm of this paper have carried out 1000 simulation experiments. The experimental results show that the algorithm can achieve more accurate positioning results in the same condition as the known Nodes. At the same time, the calculation speed of the algorithm is moderate, so the new algorithm presented in this paper is better than the traditional location algorithm.
