Data Aggregation and Fusion in WSN

What is Data Aggregation and Fusion in WSN?
Data aggregation and fusion in wireless sensor networks (WSN) combines data from multiple sensors to reduce redundancy, minimize energy consumption, and improve accuracy through in-network processing techniques.
This subtopic focuses on clustering, compressive sensing, and machine learning methods to aggregate data in resource-constrained WSN. Key approaches include genetic algorithms (Brajula et al., 2018, 29 citations), hierarchical clustering (Srinivasan et al., 2025, 19 citations), and deep learning models like SAEMDA (Qiu Lid, 2014, 6 citations). Over 100 papers address these methods for IoT applications.
Why It Matters
Data aggregation reduces transmission overhead by up to 70% in dense WSN deployments, extending network lifetime in smart agriculture (Sung et al., 2014, 10 citations; Srinivasan et al., 2025, 19 citations). It enables reliable monitoring in remote areas by fusing noisy sensor data, as shown in low-energy filtering algorithms (Fan et al., 2018, 14 citations). Applications include precision farming and environmental surveillance, where energy efficiency directly impacts scalability (Brajula et al., 2018, 29 citations).
Key Research Challenges
Energy Consumption in Clustering
Clustering algorithms like genetic-based methods drain battery life in large WSN due to frequent leader elections (Brajula et al., 2018). Balancing cluster head rotation with data fusion overhead remains difficult. Hierarchical approaches help but increase computational load on nodes (Srinivasan et al., 2025).
Data Redundancy Elimination
Explosive data growth causes redundancy, addressed by mean filtering but limited in dynamic environments (Fan et al., 2018). Immune-based fusion reduces transmissions yet struggles with heterogeneous sensors (Yang Xianze, 2009). Scalable methods for big data in WSN are needed.
Scalability in Dense Deployments
Dense IoT networks overload aggregation points, as seen in ant colony methods for agriculture (Sung et al., 2014). Fuzzy multi-hop clustering improves balance but fails in obstacle-heavy areas (Guirguis et al., 2017). Optimizing coverage with PSO hybrids is computationally intensive (Kou and Wei, 2023).
