【摘要】 无线传感器网络(WSN)被广泛使用在许多不同的场景。定位信息对传感器网络的操作是至关重要的。主要有两种类型的定位算法。基于测距的定位算法和无需测距定位算法。无需测距定位算法降低了硬件成本。但是,它只能在理想的场景中实现高精度。在本文中,我们提出一个新算法命名为基于RSSI的DV-hop算法(RDV-hop)。本算法与以往算法相比提高定位精度。更多还原

【Abstract】 Wireless sensor network(WSN) are widely used in many different scenarios.The localization information is crucial for the operation of WSN.There are mainly two types of localization algorithms.The Range-based localization algorithm and the Range-free localization algorithms.The Range-free localization algorithm reduces the hardware cost.However,it can only achieve high accuracy in ideal scenarios.In this paper,we propose a new algorithm named the RSSI-based DV-hop algorithm(RDV-hop).Our algorithm improves the localization accuracy compared with previous algorithms.更多还原
