Best insight from top research papers
The performance and reliability of WSNs differ when deployed in indoor versus outdoor environments. In indoor environments, the focus is on optimizing energy efficiency and minimizing the transmission of duplicate events to conserve power . On the other hand, in outdoor environments, the performance of WSNs is influenced by external factors such as environmental conditions and energy availability . To address these challenges, a new Environment Fusion Routing Protocol (EFRP) is proposed, which takes into account the environmental impact and selects cluster heads based on the energy and environmental factors of each node . Additionally, the reliability of WSNs in outdoor environments can be improved by considering alternative reliability strategies at different levels, such as node, cluster head, and sink . Overall, the performance and reliability of WSNs are optimized differently depending on whether they are deployed in indoor or outdoor environments.

How do wireless sensor networks differ from traditional wired sensor networks in terms of deployment and maintenance costs?5 answersWireless sensor networks (WSNs) differ from traditional wired sensor networks in deployment and maintenance costs. WSNs offer advantages like greater flexibility, scalability, and the ability to monitor multiple locations simultaneously, leading to lower installation and maintenance costs compared to wired networks. However, a significant challenge for WSNs is their limited lifetime due to battery replacements, which can be costly and time-consuming. To address this, researchers have developed energy-efficient protocols, energy harvesting techniques, and the use of renewable energy sources to improve the lifetime of WSNs. These advancements aim to reduce energy consumption, enable sensors to recharge using ambient energy sources, and provide a reliable power supply through renewable sources like solar panels, ultimately impacting deployment and maintenance costs positively.
How do environmental factors influence the selection of appropriate equipment and technologies for wireless network deployment?10 answersEnvironmental factors significantly influence the selection of appropriate equipment and technologies for wireless network deployment, as they can affect communication system availability, signal propagation, and ultimately, the performance of the network. Weather variations, including temperature, humidity, and atmospheric conditions, have been shown to impact the run-time availability of communication systems, necessitating research into better alternatives for specific regions to ensure reliable smart grid operations. Similarly, the physical environment, including obstacles and their nature, position, and mobility, plays a crucial role in the performance of wireless sensor networks (WSN), affecting the results of simulations and emulations used for evaluating new protocols and architectures.
The deployment environment's characteristics, such as climate change, necessitate the use of wireless technologies that offer low power management and resistance to noise for environmental applications, highlighting the importance of selecting the right type of wireless technology. Moreover, the range and throughput limitations of WSN can be addressed by dynamically selecting communication technology based on data requirements, environment, and geographic location, which requires multi-technologies WSN devices and efficient algorithms for Network Interface Selection (NIS).
Outdoor deployments of WSNs, for instance in forests, underscore the importance of understanding how natural outdoor environments affect network stacks, driving the need for tools and modeling techniques to address this impact. Physical parameters and atmospheric conditions also influence the accuracy and quality of wireless network-based indoor positioning algorithms, affecting the calculated position relative to the actual position. Furthermore, the surrounding environment's characteristics significantly impact the nodes' ability to communicate in a WSN, with variations induced by seasonal changes and day-night cycles.
Empirical studies on environmental signal monitoring have shown that environmental phenomena's dynamics, such as temperature, influence the system's lifetime and the cost of energy harvesting hardware, affecting the sampling frequency and, consequently, the selection of sensor nodes. Lastly, the propagation of radio signals in outdoor scenarios can be affected by factors like rainfall, foliage, path loss effect, and fading effect, necessitating optimized frequency selection for enhanced packet delivery ratios in adverse environmental scenarios.
How can indoor positioning systems be made more accurate and reliable?5 answersIndoor positioning systems can be made more accurate and reliable through various approaches. One approach is to use Ultra-Wide-Band (UWB) signals as the positioning basis, which helps to mitigate signal band interference and improve accuracy. Another approach is the use of Reconfigurable Intelligent Surfaces (RIS) to customize the Received Signal Strength (RSS) distribution in an indoor environment. RIS can manipulate the propagation of electromagnetic waves, allowing for improved wireless communication and enhanced accuracy in indoor positioning systems. Additionally, the use of improved Kalman filters and residual processing techniques can help reduce errors caused by non-line-of-sight scenarios and improve positioning accuracy.

These factors include water, air, and soil pollution, food contamination, chemical exposures, ultraviolet radiation, and climate change. Sensors are used to detect distinct environmental contaminants in a highly sensitive manner, and they provide various types of information such as location, position, and contextual elements. In the biological environment, sensors are used to monitor pH, metal ions, metabolites, viscosity, temperature, and reactive oxygen/nitrogen species.

How to design a reliable and fault-tolerant WSN topology through relay node placement optimization?5 answersTo design a reliable and fault-tolerant Wireless Sensor Network (WSN) topology through relay node placement optimization, several algorithms have been proposed. Existing algorithms have been evaluated through real-world deployments and have shown favorable performance in end-to-end delay but poor performance in reliability. To address this, Set-Covering-based Algorithm (SCA) and k-Set-Covering-based Algorithm (k SCA) have been developed. SCA ensures high-quality links by solving the Delay Constrained Relay Node Placement (DCRNP) problem while maintaining link quality above a given threshold. k SCA builds fault-tolerant WSNs by improving network reliability through fault-tolerant topology. Additionally, algorithms like cover-based 1-connected node placement (C1NP) and cover-based 2-connected node placement (C2NP) have been proposed to achieve connectivity and survivable network topologies against node failures. These algorithms have polynomial-time complexity and provide performance guarantees for the HCRNP problem.
