Abstract
This paper presents a new method based on geometric estimation and RSSI.The location of the unknown node can be estimated by the communication range of the reference node.An unknown node location can be estimated by reference to the communication overlap area of the node.The RSSI value optimization is introduced based on the geometric estimation method.The RSSI value is used to divide the geometric estimation region, and the new unknown node position is calculated by using the improved formula.The experimental results show that the proposed scheme is superior to the basic localization algorithm and has a high accuracy.At the same time, a preliminary system test is conducted in the hospital scene which gets a good positioning effect.关键词
