Abstract

The paper proposes a method to estimate the location of nodes in a sensor network. The network has a few nodes whose locations are accurately known. The other nodes estimate their location based on neighborhood relationships gathered by them through message exchanges over a wireless ad hoc network. The paper shows that by incorporating non-neighbor constraints, one can substantially improve the accuracy of location estimation as compared to only utilizing neighbor relationships. The expected location estimation error is analytically derived for a certain regular deployment. For other deployments, empirical evaluation of the proposed scheme shows that the node locations can be estimated accurately without the need for any specialized hardware.
