In the current era characterized by widespread interconnection, wireless sensor networks (WSN for short) have emerged as a very promising technological innovation. In the article entitled “Coverage Protocols for Wireless Sensor Networks: Review and Future Directions” written by Riham Elhabyan, Wei Shi, and Marc St-Hilaire in 2019, we are invited to explore this interesting world. This article opens the door into an important research domain in WSNs, with a particular focus on networking issues, and in more depth discussing relevant protocols, system models, sensing models, and corresponding deployment models. Through an in-depth understanding of the challenges and limitations faced in WSNs, the authors explain how the scientific community can guide the future development of this technology.
Wireless sensor networks are a technology with great potential and diverse applications. In the opening section of this article, the authors clearly establish the significance of WSNs in various aspects of our lives. From environmental monitoring to surveillance systems, healthcare and public safety, WSNs have opened the door to smarter and more efficient solutions. However, to fully realize its potential, network issues take center stage.
Network issues are one of the most important elements in WSN. How to monitor network areas effectively is a question that haunts researchers. This has a direct impact on sensor energy consumption and network lifetime. In an effort to find a solution, the authors emphasize the importance of proper placement of these sensors to cover specific areas of interest in the network. With so many factors at play in this issue, this article aims to facilitate a more comprehensive understanding of this issue and its impact on wireless sensor networks.
However, this article does not just concentrate on defining the problem. One striking aspect is the focus on network protocols. The authors explore the various existing protocols and discuss their characteristics carefully. This is an important step because network protocols are the “heart” of WSN. The results of this in-depth analysis help readers understand the strengths and weaknesses of each existing protocol.
It is important to remember that in the world of research, often the main challenge is how to deal with unrealistic assumptions. this article notes that many network protocols make unrealistic assumptions about the underlying system model. This is an important insight because it reminds us that in technology design, we must ensure that the models used are in line with reality. It also shows that improvements in this area have the potential to lead to better precision and efficiency in networks.
Next, it is important to consider the physical characteristics of the sensor node itself. This article addresses this issue by exploring network-aware deployment protocols. Why is this important? Because the physical characteristics of sensor nodes can influence how networking is performed. There may be nodes with higher battery power or different signal sensitivity. Therefore, considering these physical attributes in network protocol design is a wise move.
However, does this article only address that issue? Certainly not. It also provides an inspiring look at the future of today’s technology. One of the key points is the need for a more realistic network model for the sensor nodes in the network. This will help overcome the previously mentioned problem of unrealistic assumptions.
In addition, it is also important to consider energy aspects in network protocol design. Idealized energy consumption models often do not reflect real-world situations. Therefore, this article provides valuable suggestions by proposing the use of discrete radio models for more accurate power consumption calculations. This is a practical and relevant step in the development of WSN technology.
Next, this article considers network connectivity. The use of the term “connectivity” may sound technical, but it is essentially about ensuring that these sensors can communicate effectively with each other. When we talk about effective networking, connectivity becomes a key factor. this article emphasizes how important it is to consider these factors in designing future WSN solutions.
Furthermore, this article emphasizes the need for more realistic sensing models. Why? Because sensing is at the heart of what sensors do. These models should reflect the anisotropic nature of WSNs to more accurately address network problems. This reminds us that in the world of technology, precision is everything.
