The proliferation of sensor networks has led to an exponential increase in data generation, presenting significant challenges for effective management and analysis. This surge in data volume, velocity, and variety necessitates robust solutions for acquisition, storage, processing, and insightful analysis. The complexity of handling these massive datasets from sensor-based Internet of Things (IoT) systems is a primary concern, requiring scalable architectures and advanced analytics to extract meaningful information [1].
Ensuring the quality of data collected by sensors is paramount, as it directly impacts the reliability of big data analytics. Various factors can degrade sensor data quality, including noise, missing values, and sensor drift, which can lead to inaccurate decision-making in critical cyber-physical systems. Therefore, frameworks incorporating data cleaning, validation, and fusion techniques are essential to maintain high-quality sensor data [2].
The geographical distribution of sensors and the sheer volume of data often make centralized processing inefficient. Edge computing emerges as a vital solution by enabling data processing closer to the source, reducing latency, bandwidth consumption, and enhancing privacy. This distributed approach is crucial for real-time applications demanding immediate insights from sensor networks [3].
Managing the storage and transmission burdens associated with massive sensor data is a continuous challenge. Novel data compression techniques, both lossless and lossy, are being developed to significantly reduce data size with minimal impact on analytical accuracy. These advancements are critical for enabling more efficient big data management in resource-constrained environments [4].
As sensor data volumes continue to grow, scalable distributed storage systems are indispensable. These systems must effectively handle the influx of data by employing strategies such as data partitioning, replication, and fault tolerance. Ensuring continuous availability and efficient querying of historical sensor data is key for comprehensive big data analytics [5].
Analyzing large-scale sensor data often involves identifying anomalies and understanding complex patterns. Machine learning algorithms, particularly deep learning, are being leveraged for real-time anomaly detection in sensor-based big data streams. Adaptive learning models are crucial for coping with the dynamic nature of sensor data and evolving anomalies [6].
Heterogeneous sensor networks generate data from diverse sources, posing challenges for synchronization and integration. Semantic-based approaches are crucial for reconciling data from various sensors, ensuring consistency and enabling unified analysis. Effective metadata management and ontology mapping are vital for achieving comprehensive data fusion [7].
The collection and processing of extensive sensor data raise significant privacy and security concerns. Protecting sensitive information requires the implementation of advanced cryptographic techniques and anonymization methods. A secure data management framework is necessary to balance data utility with stringent privacy requirements [8].
To enhance trust and accountability in sensor data management, blockchain technology offers a promising solution. A decentralized blockchain framework can provide immutable records of sensor data transactions, preventing tampering and ensuring data integrity. This is particularly important for critical infrastructure applications requiring high levels of transparency [9].
Integrating stream processing technologies with big data management systems is essential for sensor data analytics. This integration enables real-time insights from continuous sensor data streams, facilitating timely decision-making. Architectures like Apache Kafka and Flink are instrumental in handling high-velocity data effectively [10].
The ever-increasing volume of data generated by sensor networks poses substantial obstacles in terms of acquisition, storage, processing, and analysis. Addressing these challenges requires the development of scalable architectures and sophisticated analytical tools to glean meaningful intelligence from sensor-based IoT systems. The efficient handling of massive datasets is a critical area of research and development, driving innovation in data management strategies [1].
A fundamental aspect of effective big data analytics from sensor networks is the assurance of data quality. Issues such as noise, missing values, and sensor drift can significantly compromise the reliability of analytical outcomes. Consequently, the implementation of comprehensive frameworks that include data cleaning, validation, and fusion mechanisms is vital for ensuring the integrity of sensor data used in downstream applications [2].
In scenarios involving geographically dispersed sensors and large data volumes, centralized processing is often impractical. Edge computing offers a compelling alternative by bringing computation closer to the data source. This approach not only reduces latency and bandwidth demands but also enhances data privacy. The adoption of edge computing is increasingly important for applications that require immediate and actionable insights [3].
Minimizing the storage and transmission overhead associated with sensor data is a persistent challenge. Significant advancements have been made in data compression techniques, encompassing both lossless and lossy methods tailored for sensor data characteristics. These techniques are crucial for optimizing the use of storage and network resources, thereby facilitating more efficient big data management [4].
As the scale of sensor data continues to expand, the need for robust and scalable distributed storage systems becomes more pronounced. Such systems must be adept at managing high data volumes and velocities, employing effective strategies for data partitioning, replication, and fault tolerance. This ensures continuous data availability and facilitates efficient querying for analytical purposes [5].

Data synchronization and integration present considerable challenges in heterogeneous sensor networks. Semantic-based approaches are employed to reconcile data from disparate sources, ensuring consistency and enabling unified analytical efforts. Effective metadata management and ontology mapping are indispensable for achieving comprehensive data fusion and deriving richer insights [7].
Privacy and security are paramount concerns when dealing with the vast amounts of sensor data being collected and processed. The implementation of sophisticated cryptographic techniques and anonymization methods is essential for safeguarding sensitive information. A well-designed data management framework must strike a balance between data utility and the imperative for robust privacy protection [8].
The utilization of blockchain technology offers a novel avenue for enhancing the security and transparency of sensor data management. By providing an immutable and decentralized ledger for data transactions, blockchain ensures data integrity and fosters greater trust and accountability. This is particularly beneficial for critical applications where data tampering must be prevented [9].
