摘要:
无线传感器网络定位技术是无线传感器网络中的关键技术之一。该研究基于无线电干涉定位系统(RIPS)建立了等价测量误差模型,研究实际情况下已定位节点作为未知节点的锚节点在进行定位的过程中,由于锚节点自身位置误差对未知节点定位的精度影响以及误差传播问题。通过仿真分析表明,锚节点自身位置误差会降低未知节点的定位精度。在此基础上考虑锚节点身位置误差传播的影响研究无线传感器网络定位节点分配策略,在定位过程中找到最优锚节点使得定位误差最小化。
Abstract:
Sensor localization is one of the key technologies of wireless sensor networks. This paper establishes an equivalent measurement error model based on radio interferometric positioning system (RIPS), and investigates the node positioning error and error propagation caused by the position error of anchor nodes in practical situations. Simulation result shows that the position error of anchor nodes will reduce the positioning accuracy of unknown nodes. On this basis,research wireless sensor network localization node allocation strategy considering the influence of anchor node position error propagation, so as to find the optimal anchor node to minimize positioning error during the positioning process.
