A new energy aware cluster head selection for LEACH in wireless sensor networks

Internet of Things (IoTs) as a new network pattern for the intelligent world usually uses wireless sensor networks (WSNs) perception layer which consisted numerous number nodes scattered in environment to gather intended information. The selected information then is sent base station (BS) be cloud server further processing. Since energy limited, most significant challenge these reducing consumption network. It proved that dividing clusters can significantly reduce consumption. One popular clustering protocols WSNs Low-Energy Adaptive Clustering Hierarchy (LEACH). In this protocol, cluster heads (CHs) are randomly results poor performance real scenarios. article, aware CH selection algorithm proposed selects CHs based on residual energy, position and centrality nodes. variable range upon neighbours each node calculated. Simulation show outperforms LEACH, Multi-hope Routing with LEACH (MR-LEACH) Enhanced Multi-hop (EM-LEACH) terms consumption, increasing lifetime improving reliability.
