Mitigating anchor misplacement errors in wireless sensor networks

Localization errors posed by anchor misplacement have generally been overlooked in localization research. Previous studies in this field were focused on measurement errors. In this paper, we study the effects of anchor node misplacement, in terms of distance rather than orientation, on the localization error. We propose a distributed and deterministic detection algorithm to identify misplaced anchor nodes and to discard them. We evaluate the performance of our proposed algorithm, and compare it to the algorithm in. Results show that our proposed algorithm is far more conducive to wireless sensor networks (WSNs), results in higher detection rates of misplaced anchors, and provides more effective mitigation.
