Background & Objective: The demand of Wireless sensor networks have elevated
exceedingly by virtue of broad capability of the sensor networks to relate the physical
environment. Sensor devices depend on battery capability and are deployed in adverse
environments and it becomes extremely difficult to replace. Thus, elaborating the energy of sensor
nodes becomes vital.
Methods: G-LEACH is proposed by introducing competent cluster head replacement strategy and
adding a relay node to increase the network stability and node lifetime.
Results & Conclusion: Simulation is performed in NS-2. The proposed G-LEACH is examined
with existing LEACH and MODLEACH protocols and the simulation results depicts that GLEACH
outperforms the conventional LEACH and MODLEACH and thereby enhancing the
lifetime by rotating the CHs and minimizing the energy dissipation.
