Table 6 The statistics of alive nodes of four algorithms in 300 × 300m2
From: A modified cluster-head selection algorithm in wireless sensor networks based on LEACH
Network lifetime | FND | HNA | LND |
|---|---|---|---|
LEACH | 210 s | 350 s | 480 s |
LEACH-C | 300 s | 400 s | 510 s |
EE-LEACH | 330 s | 470 s | 550 s |
LEACH-M | 400 s | 510 s | 590 s |
Improvement ratio of LEACH-M | 33%/21% | 28%/9% | 16%/7% |
