I-HHCA : An Improved Hybrid Hierarchical Clustering Approach for Wireless Sensor Networks
摘要
Enhancing the longevity and scalability of wireless sensor networks (WSNs) is achieved through the optimization of communication distances. To achieve this, a hierarchical clustering algorithm is employed, which helps conserve energy by facilitating efficient data collection and transmission among nodes. While previous clustering methods predominantly utilized a two-level hierarchy, limited attention has been given to a three-level framework. In our study, we introduce a clustering approach based on a three-level hierarchy, incorporating both centralized and distributed algorithms for the selection of upper-level and lower-level heads. The simulation results suggest that this novel technique performs effectively in improving network performance.
