摘　　要：为了提高无线传感器网络定位精度,应用果蝇算法(fruit fly optimization algorithm,FOA)-蒙特卡罗锚盒(Monte Carlo anchor box,MCB)算法对无线传感器网络(wireless sensor network,WSN)系统中移动节点进行定位建模,分析了移动速度、锚节点密度和样本数对定位精度的影响。研究结果表明:FOA优化MCB算法具有比MCB算法更优的定位精度,当节点移动速度变大后可以获得更小的定位误差,在10 m/s的速度下获得了最低误差值情况下锚节点数量和移动节点定位误差之间的变化曲线;当锚节点较少时,MCB与FOA优化MCB形成了较大的定位误差;随样本数增大,定位误差逐渐减小,在样本数达到150时获得一个稳定的定位误差。研究对无线传感器网络定位精度具有很好的应用价值,易于实现推广。In order to improve the positioning accuracy of wireless sensor network(WSN),the fruit fly optimization algorithm(FOA)optimized Monte Carlo anchor box(MCB)movement algorithm was used to model the positioning of mobile nodes in WSN application system,and the influence of movement speed,anchor node density and sample size on positioning accuracy was analyzed.The research results show that FOA optimized MCB algorithm has better positioning accuracy than MCB algorithm.When the node moving speed increases,a smaller positioning error can be obtained.The lowest error value can be obtained at the speed of 10 m/s;the change curve exists between the number of anchor nodes and the positioning error of mobile nodes at 10 m/s;when there are fewer anchor nodes,a larger positioning error forms between MCB and FOA optimized MCB;as the number of samples increases,the positioning error will gradually reduce,and a stable positioning error will be obtained until the number of samples reaches 150.The research is of great application value to the positioning accuracy of WSN and easy to be popularized.
