We describe a new algorithm for sensor network localization based on short intersensor distances and fully decentralized computation. The algorithm computes local coordinates of small “patches” of sensors and glues them together using a distributed global optimization process. Thanks to the global optimization, our method is more robust in the presence of noisy measurements than existing incremental methods. Most notably, and unlike some other global optimization techniques, our method cannot… CONTINUE READING
