Often, this feature is especially important in applications such as environmental monitoring. This is where the deployment is frequent for several months or years at a time.

• Scalability

  Often, WSNs are designed to be scalable, allowing easy expansion or reduction of the system as per the current needs. Conventionally, adding more sensor nodes is applicable without needing a major overhaul of the existing infrastructure. This makes these networks flexible to changing demands. Also, scalability ensures that WSNs can manage variable data loads. Moreover, it supports diverse applications ranging from small-scale monitoring projects to large ones requiring extensive coverage.

• Data Processing and Analysis

  Commonly, data processing and analysis is a key feature of wireless sensor networks. Ideally, after collecting data, most WSNs perform local data processing on the sensor nodes prior to transmission. This technique helps in minimizing the amount of data sent over the network. Thus, it optimizes bandwidth usage. Besides, many networks employ advanced algorithms for data filtering, aggregation, and compression. This enhances efficiency and offers real-time insights into monitored conditions.

• Multihop Communication

  Apart from direct communication with the base station, normally, many WSNs utilize a multihop communication mechanism. Often, this allows the sensor nodes to relay data to each other until the information reaches its destination. Ideally, multihop communication improves transmission reliability. In addition, it extends the network's range by enabling nodes located far from the base station to communicate effectively. Also, this feature is crucial in scenarios where the deployment density of sensors is low.

• Robustness and Fault Tolerance

  Normally, robustness and fault tolerance are key features of wireless sensor networks. Also, these networks are constructed to withstand node failures or environmental challenges. Often, due to their decentralized nature, WSNs automatically adjust to maintain operations even when some nodes go offline. Commonly, this ensures that the network continues to deliver reliable data. Most importantly, it minimizes disruptions in critical applications such as healthcare monitoring and infrastructure surveillance.

Commercial use cases of Wireless Sensor Network
