本程序用资源分配网(Resource_Allocation Network,简称RAN)实现了Hermit多项式在线学习问题。训练样本产生方式如下,样本数400,每个样本输入Xi在区间[-4,4]内随机产生(均匀分布),相关样本输出为F(Xi) = 1.1(1-Xi + Xi2)exp(-Xi2/2),测试样本输入在[-4,+4]内以0.04为间隔等距产生,共201个样本。训练结束后的隐节点为:11个,训练结束后的平均误差可达:0.03

改进DV-Hop定位算法
首先设置初始量,布置了一个范围为100×100m2的区域,其上随机分布100个传感器节点,其中有10个信标节点,节点的通信半径为30m。
第二步在正方形区域内产生均匀分布的随机拓扑,随机产生节点坐标并将其中十个选定为信标节点,其余九十个设为未知节点,然后画出节点分布图。
第三步通过最短路径法计算未知节点与每个信标节点的最小跳数。
第四步根据前面记录的其他信标节点的位置信息和相距跳数估算平均每跳的实际距离,用跳数估计距离的方法得出未知节点到信标节点的距离。
