This paper extends the ant colony algorithm which is used for solving 0-1 knapsack problem in reference [7], and gets enlightenment from the ant colony algorithm with 2-opt local optimization for solving traveling salesman problems: Exchange strategy can make the algorithm have faster convergence rate and get better quality solution. So this paper presents the ant colony algorithm based on exchange stragegy.

本文推广了文献[7]中求解单维0-1背包问题的蚁群算法，并从结合2-opt等局部优化的蚁群算法求解旅行商问题中得到启示：通过交换策略可以加快算法的收敛速度和获取更高质量的解，因此提出了基于交换策略的蚁群算法。

This thesis proposes multi-components of Gaussian model to get much close description for the received signal strength. Also, this thesis adopts Excitor to approach a 99% exactly positioning for some specific field application such as surveillance desired application. In addition, this thesis presents a smoothing filter to adjust the moving path therefore the movement path shown in computer graphical interface may looks fluently, in addition, RSSI filter also improve position accuracy.

此篇论文采用混合高斯模型来描述实际复杂的讯号强度接收情况，此外，某些特殊领域的定位需求，例如：工地安全等，也搭配了双频定位器来辅助整个定位系统在必要的定位点具备99%的定位精度；最后，此篇论文亦搭载了平滑滤波器来调整目标移动的路径记录，以使在电脑画面路径的追溯上，达到更平滑的效果，此外，接收讯号强度滤波器亦具改善定位精度的效果。
