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。

传统的高分辨波达方向(DOA)估计算法中,一般都假设信号位于远场,此时入射到阵列的信源波前为平面波前,空间信号的定位参数可由DOA来确定。然而,当信源处于阵列的Fresnel区域时,信号波前需用球面波来描述,每个信源的定位信息要用DOA和距离联合描述。因此,远场情况下的一些线性理论推导已不再成立,传统的远场算法的估计不再适用(In traditional high resolution direction of arrival (DOA) estimation algorithms, it is
