【摘要】 给出了无线移动AdHoc网络的一个节点定位概率模型,证明了当平面网络中的已知节点达到一定的数量要求时,通过模型算法可以充分准确地确定未知节点的位置.通过仿真分析,说明该模型在实际中是可行的、有效的;并且分析了节点移动性对未知节点定位的影响,得出未知节点的定位是随着其移动速度的增大而变得愈加困难,而随着其与已知节点的通信距离的增大而变得愈加容易的结论.更多还原

【Abstract】 A node positioning probabilistic model is presented for wireless mobile Ad Hoc networks, by which we proof that an unknown node is able to be uniformly located when the known nodes in the plain networks is qualified to a certainty scalar for the model. The model availability is illuminated by means of computer simulations. Furthermore, the impact of positioning of unknown node due to node mobility is analyzed and resulted in mobility increase the difficulties of positioning unknown node and, in the other hand, increasing the communication space decrease the difficulties of positioning unknown node.更多还原
