摘要
为了满足矿井安全监测和人员定位的要求,提出了一种改进的DV-Hop算法.其主要特点是考虑了定位过程中所利用的导标节点之间的位置关系及与未知节点之间的几何拓扑关系,然后依据一定的原则对参与定位的导标节点进行选择,改进后的定位方法相比原DV-Hop算法具备更优的定位精确度,其适用性也更为广泛.
In order to meet mine safety monitoring and personnel requirements of position,an improved DV-Hop algorithm is proposed. The main features of this approach is to consider the use of the position marked the relationship between beacon nodes and the geometric topological relationship between beacon nodes with unknown nodes in the positioning process,then based on certain principles to select the beacon nodes which are involved in positioning. This improved method of positioning compared to the original DV-Hop algorithm has better positioning accuracy and its applicability is also become more and more extensive.
