摘要 提出了一种自适应的自组织网络定位方案,它适用于节点分布比较集中的自组织网络,能有效解决复杂地形环境下的应用问题。该方案采用到达时间(TOA)测量值作为参数,结合非视距误差消除技术,并根据定位的QoS和网络的拓扑变化情况自适应地调整定位参数。仿真表明,它能提高定位精度和可定位性能,改善网络适应性。 This paper proposes a self-adaptive localization method in ad-hoc network. It is fit for an ad-hoc network which deploys in irregular terrain condition and has higher node density. It uses the measurements of time-of-arrival (TOA) and a NLOS error mitigation scheme based on TOA reconstruction. The method adjusts the positioning parameters self-adaptively according to QoS and dynamical topology. The simulations show that presented method exhibits higher accuracy, localization extent and applicability .
