Due to the energy resource restriction, the sensor nodes drain out their power. Therefore the routing mechanism among nodes and sink need to consider the balanced energy utilization. Low-Energy Adaptive Clustering Hierarchy (LEACH) consider direct data communication from source cluster head to sink, which results unbalanced energy consumption of cluster heads CHs and leads to routing holes in the network. For balanced energy consumption and maximum network lifetime an Energy efficient Least Edge Computation routing protocol (ELEC) is proposed in literature. The simulation results show better performance of ELEC as compared to LEACH. Therefore, an energy-efficient least edge computation multi-hop clustering LEACH (ELEC-LEACH) is proposed, where the LEACH routing protocol is modified by merging the ELEC multi-hop routing protocol with it. Simulation results prove that ELEC-LEACH …
