Acoustic Target Location Based on RSSI in WSN

摘要

Acoustic target location is an important question in W'SN's application study. It is difficult to make a quick target location with high location accuracy under the condition that the sensor notes are random distributed. The article converts acoustic target location to optimization of likelihood function based on RSSI of acoustic signal in twodimension space. Then, it makes out the global optimum solution using DFP method in optimization theory. The emulation result shows that the method meets the need of rapid and accurate location and possesses practical application value.
