Some WSN by lots of immobile node and with the restricted energy and while not further charge of energy. Whereas extension of the many sensing element nodes and their operation. Therefore, it is normal. Inactive nodes miss their communication in network. For this, the authors tend to proposes a Fault Node Recovery (FNR) rule to boost the lifespan of a Wireless Sensing element Network (WSN) once a number of the sensing element nodes finish off, either as a result of they not have battery energy or they need reached their operational threshold. Exploitation the FNR rule may end up in fewer replacements of sensing element nodes and additional reused routing ways.
