Geometric Buildup Algorithms for Sensor Network Localization
Algorithm 4
The two-phase geometric buildup algorithm.
Input: The positions of the anchors, the distances . | Output: The positions of a set of determined sensors. | Step 1: Phase 1: | Set the anchors to be the initial set of sensors. | Apply the extended geometric buildup algorithm. | Step 2: If the percentage of the undetermined sensors is greater than TH. | Phase 2: | Find and determine an initial set of sensors. | Apply the extended geometric buildup algorithm. | Step 3: Align the sensors determined in the two phases. |
