| IMFES: |
| Input: A set of wireless nodes, . |
| Output: A -fault resistant energy-t-spanner. |
| First Step: |
| 1: Compute original topology |
| 2: For each edge , compute |
| 3: sort all edges in by ascending weight. |
| 4: |
| 5: For each edge in |
| 6: if u and v is not k connected in |
| 7: |
| 8: |
| 9: else if all nodes are k connected in |
| 10: go to step two |
| 11: end if |
| 12: end for |
| Second Step: |
| 13: For each edge |
| 14: if |
| 15: |
| 16: end if |
| 17: end for |
| 18: Return |
