Algorithm 4
Localize the unknown node with two neighbour references.
| Input: unknown node and its neighbour references | | Output: estimated position of if can be localized | | measured distances of to | | positions of | | roots of | | if then | | return | | else | | | | if = then | | return cannot be localized | | end if | | | | if then | | return | | else | | | | if then | | | | else | | | | end if | | solution of Algorithm 3 using as inputs | | return | | end if | | end if |
