Energy Efficient Routing Protocol Using a Relay Node in Wireless Sensor Networks

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.
