摘要

传感器定位已成为无线传感器网络(WSN)实际应用的基本要求。然而，无线电传播的不规则性和硬件成本的严格限制给无线传感器网络的定位带来了很大的挑战。无距离定位比基于距离的定位更有吸引力，因为它们不依赖于接收到的信号强度来估计距离，因此只需要简单廉价的硬件。在本文中，我们提出了一种基于接收信号强度指标比较(ROCRSSI)的环重叠无距离方法。仿真结果验证了该方法具有较高的估计精度。

Sensor localization with Ring Overlapping based on Comparison of Received Signal Strength Indicator

Sensor localization has become an essential requirement for realistic applications over wireless sensor networks (WSN). Radio propagation irregularity and the stringent constraint on hardware cost, however, make localization in WSN very challenging. Range-free localizations are more appealing than range-based ones, since they do not depend on received signal strength to estimate distance and thus need simple and cheap hardware only. In this paper, we propose a ring-overlapping, range-free approach using the Ring Overlapping based on Comparison of Received Signal Strength Indicator (ROCRSSI). Simulation results have verified the high estimation accuracy achieved with ROCRSSI.
