Abstract

A hybrid localization method and a wireless network that performs the method are disclosed herein. In an embodiment of a hybrid localization technique, one or more sensor nodes in the network switch between different localization techniques depending on location area conditions. This technique chooses the most accurate localization technique for the given location area conditions, and thus potentially provides the best possible location accuracy for those conditions. A representative set of simulations and experiments verify the potential performance improvement realized with embodiments of the hybrid localization technique.
