Symbol | Description |
N | Number of nodes in swarm |
| Number of communication identifiers in use |
| Number of nodes within communication radius |
| Communication radius of nodes |
| Graph with reconstructed nodes indicating positions as vertex and distance between nodes as edges |
| Unique (hardware) identification number (UID) of nodes i and j, other letters are also used to indicate other nodes. An additional bar in the indication stresses these are the true values (opposed to measured or hypothesised) |
| Communication identification number (CID) used by node i |
| Distance between node i and node j. Additional bars in the indication stress that these are true values (opposed to measured of hypothesised). |
| Position of node i |
| Consistency function used for associating measured distances from two nodes into a mutual connection |
| Threshold value for maximum allowed distance deviation in consistency condition |
| Set of hypothesised distances between node i and j |
| Number of additional identity ambiguities |
| Number of additional distance ambiguities |
| Individual nodes (small letter) in a set of nodes (capital) selected based on some criteria in reconstruction algorithm |
| Cliques in already reconstructed graph |
| Recall percentages of nodes that have been reconstructed; Y and Z have an additional condition on the accuracy of the reconstruction |
| Error metrics of a reconstruction indicating the mean absolute squared error of the reconstructed positions |
| Error metric of a reconstruction indicating the relative error of the reconstructed distances |
| Different noise parameters of distance measurements, expressed in percentages. Index indicates type of noise. |
