Abstract
Range-based localization of wireless sensor networks is to obtain sensory data for the calculation of the distance to the target. The positioning accuracy is directly affected by environmental factors. The major localization error of the traditional methods will be made by the use of fixed parameters for the measurement of distance. In this chapter, we proposed a RSSI-based cooperative localization algorithm by adjusting the signal propagation model dynamically. The localization method was optimized and the triangular range localization method was taken as an example to verify the optimization result. From the simulation and experiment, we verify that the proposed algorithm can provide higher localization accuracy.
