This paper proposes a novel and computationally efficient global I< optimization method based on swarm ntelligence for locating ti nodes in a WSN environment. The mean squared range error of a all neighbouring anchor nodes is taken as the obj

子群优化算法，并把次算法用于求解旅行商问题．为了增强算法的局部搜索能力，在改进的算法中加入倒置，局部搜索等方法，同时利用遗传算法的全局搜索能力强的特点对求到的解再进行优化，同时，对于搜索全局最优路径方面，通过应用消除交叉路径的方法进行了优化．-Sub swarm optimization algorithm, and the second algorithm is used to solve the traveling salesman problem. In order to enhance
