Abstract:

Localization is one of the supporting technologies in wireless sensor networks. Based on summing-up of literature and research about location algorithm, six representative Range-Free self-location algorithms were introduced in this paper. Using Matlab, network topology was constructed to simulate the six algorithms, of which performance was compared and summarized in the end of this paper, with some important difficulties needed to be solved for the future research about location algorithm for wireless sensor network.
