Cluster-based routing protocols offer advantages such as improved power control, reduced control messages, enhanced resource allocation and bandwidth re-usability. Low Energy Adaptive Clustering Hierarchy (LEACH) a cluster-based protocol includes distributed cluster formation. LEACH randomly selects sensor nodes as cluster-heads and rotates them to distribute energy load uniformly among network sensors. LEACH is ambiguous sensor nodes position and network Cluster Head (CH) numbers. This study proposes a hybrid BAT algorithm (HBA) with Differential Evolution (DE) to improve the efficiency and to overcome disadvantages of LEACH Simulation study revealed that the HBA achieved improved throughput, lowered delay and packets retransmission and better data dropped than LEACH
