Table 2 Computational complexity analysis.
Stage | Parameters | Time Complexity |
|---|---|---|
Fuzzy-BIRCH insertion | N nodes, B branching factor | \(O(N log B)\) |
Periodic FCM update | c centroids, k clusters, I iters | \(O(I\cdot k\cdot c)\) |
Sleep–Wake scheduling | N nodes | \(O(N)\) |
FFO CH selection | \(P, m, I\_ffo\) | \(O(P\cdot m\cdot I\_ffo)\) |
TCN-BiGRU inference | L, H | \(O(L \cdot H^{2} )\) |
Training (offline) | S samples, E epochs | \(O(E\cdot S\cdot cost)\) |
