Query: Triangle Extension: Efficient Localizability Detection in Wireless
  Sensor Networks   Determining whether nodes can be localized, called localizability detection,
is essential for wireless sensor networks (WSNs). This step is required for
localizing nodes, achieving low-cost deployments, and identifying prerequisites
in location-based applications. Centralized graph algorithms are inapplicable
to a resource-limited WSN because of their high computation and communication
costs, whereas distributed approaches may miss a large number of theoretically
localizable nodes in a resource-limited WSN. In this paper, we propose an
efficient and effective distributed approach in order to address this problem.
Furthermore, we prove the correctness of our algorithm and analyze the reasons
our algorithm can find more localizable nodes while requiring fewer known
location nodes than existing algorithms, under the same network configurations.
The time complexity of our algorithm is linear with respect to the number of
nodes in a network. We conduct both simulations and real-world WSN experiments
to evaluate our algorithm under various network settings. The results show that
our algorithm significantly outperforms the existing algorithms in terms of
both the latency and the accuracy of localizability detection.
