Wireless Sensor Networks (WSNs) are foundational to the advancement of smart applications across a multitude of domains. Their ability to collect, transmit, and process data from the physical environment in real-time has made them indispensable for creating intelligent and responsive systems. The design and optimization of these networks are paramount to ensuring their effectiveness, reliability, and scalability. Critical design considerations, including energy efficiency, data aggregation, network topology, and robust security mechanisms, are essential for deploying WSNs in diverse smart environments, ranging from interconnected homes to complex industrial Internet of Things (IoT) ecosystems. A holistic approach, meticulously balancing performance, cost-effectiveness, and long-term sustainability, is therefore crucial for the successful implementation of WSNs in these advanced smart applications [1].
As smart cities evolve, the demand for efficient and intelligent infrastructure grows exponentially. WSNs play a pivotal role in enabling this transformation by facilitating the collection of vast amounts of data related to urban services, environmental monitoring, and public safety. In this context, the development of energy-efficient routing protocols becomes a critical area of research. Addressing the inherent challenge of limited battery life in sensor nodes, these protocols aim to minimize redundant transmissions and optimize path selection to extend network operational longevity. The key takeaway from such research is the significant improvement in network lifetime and the substantial reduction in energy consumption that can be achieved through intelligent routing decisions tailored for IoT-enabled smart city applications [2].
Smart agriculture is another domain where WSNs are revolutionizing operational efficiency and sustainability. The ability to monitor environmental conditions, crop health, and resource utilization with high precision enables farmers to make more informed decisions. Within WSNs for smart agriculture, the optimization of data aggregation techniques is a significant focus. Novel approaches are being introduced to effectively reduce data redundancy and minimize communication overhead, thereby conserving precious energy resources and markedly improving the efficiency of data collection from agricultural sensors. The main contribution of this line of research lies in demonstrating how smarter data processing directly at the sensor nodes can significantly enhance overall network performance [3].
Smart grids represent a complex and dynamic infrastructure where WSNs are vital for monitoring, control, and efficient energy distribution. The performance and energy consumption of WSNs within these critical applications are heavily influenced by their network topology.
