摘要
基于RSSI的测距是一种低成本的距离测量技术。在分析影响RSSI测距误差的因素后,根据实际情况设计一种用于修正RSSI测距误差的方法,以减少由各种综合性因素引起的测距误差给节点定位带来的不良影响。理论分析和仿真结果表明,该修正方法可以有效地降低节点的定位误差。
RSSI-based ranging is a low-cost distance measuring technology. After analyzing the factors influencing RSSl-based ranging error, an error amending method is devised according to the actual conditions, to decrease the bad effect on node localization brought by the ranging error from various synthesized factors. The theoretical analysis and simulation results prove that the amending method can decrease the node localization error effectively.
