Wireless sensor networks (WSNs) require energy management protocols to efficiently use the energy sup-ply constraints of battery-powered sensors to prolong its network lifetime. This paper proposes a novelHeuristic Algorithm for Clustering Hierarchy (HACH).The clustering algorithm uses a novel heuristic crossover operator tocombine two different solutions to achieve an improved solution that enhances the distribution of cluster head nodes and coordinates energy consumption in WSNs. We have evaluated the performance of the proposed technique with existing technique i.e. tree-based on the following metrics i.e. stability period, network lifetime, residual energy (average remaining energy), and throughput. The proposed algorithm is evaluated viasimulation experiments and compared with some existing algorithms. Our protocol shows improvedperformance in terms of extended lifetime and maintains favourable performances even under differentenergy heterogeneity settings.
