Special Issue Information

Dear Colleagues,

Wireless Sensor Network (WSN) is an infrastructure-less wireless network, which is used to deploy a large number of wireless sensors for monitoring physical and environmental conditions. There are four key components in WSN, namely sensor node, radio node, access point, and evaluation software. WSN has many applications such as monitoring the environment, threat detection, noise level of surroundings, patient monitoring, agriculture, and many more. Internet of Things (IoT) exists at a higher level than WSN. Essentially, WSN is a technology used within an IoT system. It is a network of interconnected computing devices, mechanical and digital machinery, objects, animals, and people, all of which are assigned unique identification. Each thing or device is uniquely identifiable through its embedded computing system. The growing usage of internet devices in different scenarios makes the Quality of Service (QoS) a major issue in WSN for IoT applications. Here, each application has its requirements of QoS and customers can set their own QoS criteria based on their demands. To support secure and predictable services, QoS manages delays, delay variation, bandwidth and packet loss by classifying traffic, and registering channel limits. Because of the untrustworthy characteristics of WSN for IoT applications, data may be processed using different techniques in various applications that can affect the QoS. Thus, providing QoS is a challenging task.

This Special Issue intends to invite scholars, researchers, engineers, and other innovators to collectively show their state-of-the-art knowledge and their cutting-edge innovations in QoS in Wireless Sensor Network for IoT Applications. Theoretical investigation and prototype implementation-based studies are particularly welcomed. Topics of interest include, but are not limited to:

  • Modelling and improving QoS in WSN for IoT applications;
  • QoS-based routing protocols in WSN;
  • QoS in smart grid applications;
  • QoS differentiation management in WSN for IoT applications;
  • Metrics of QoS in WSN for IoT applications;
  • Implementation of QoS in WSN for IoT applications;
  • QoS in lightweight IoT applications;
  • QoS in cloud-based IoT applications;
  • QoS in database management;
  • Sustainable QoS solutions.

In the quest to optimize user experience, network, and service, providers continually seek to deliver high-quality content tailored to individual preferences. However, predicting user perception of quality remains a challenging task, given the subjective nature of human perception and the plethora of technical attributes that contribute to the overall viewing experience. Thus, we introduce a Fuzzy Logic-bAsed ModEl for Video Quality Assessment (FLAME-VQA), leveraging the LIVE-YT-HFR database containing 480 video sequences and subjective ratings of their quality from 85 test subjects. The proposed model addresses the challenges of assessing user perception by capturing the intricacies of individual preferences and video attributes using fuzzy logic. It operates with four input parameters: video frame rate, compression rate, and spatio-temporal information. The Spearman Rank–Order Correlation Coefficient (SROCC) and Pearson Correlation Coefficient (PCC) show a high correlation between the output and the ground truth. For the training, test, and complete dataset, SROCC equals 0.8977, 0.8455, and 0.8961, respectively, while PCC equals 0.9096, 0.8632, and 0.9086, respectively. The model outperforms comparative models tested on the same dataset. Full article

Wireless sensor network (WSN) environment monitoring and smart city applications present challenges for maintaining network connectivity when, for example, dynamic events occur. Such applications can benefit from recent technologies such as software-defined networks (SDNs) and network virtualization to support network flexibility and offer validation for a physical network. This paper aims to present a testbed-based, software-defined wireless sensor network (SDWSN) for IoT applications with a focus on promoting the approach of virtual network testing and analysis prior to physical network implementation to monitor and repair any network failures. Herein, physical network implementation employing hardware boards such as Texas Instruments CC2538 (TI CC2538) and TI CC1352R sensor nodes is presented and designed based on virtual WSN- based clustering for stationary and dynamic networks use cases. The key performance indicators such as evaluating node (such as a gateway node to the Internet) connection capability based on packet drop and energy consumption virtually and physically are discussed. According to the test findings, the proposed software-defined physical network benefited from “prior-to-implementation” analysis via virtualization, as the performance of both virtual and physical networks is comparable.

The Internet of Medical Things (IoMT) overcomes the flaws in the traditional healthcare system by enabling remote administration, more effective use of resources, and the mobility of medical devices to fulfil the patient’s needs. The IoMT makes it simple to review the patient’s cloud-based medical history in addition to allowing the doctor to keep a close eye on the patient’s condition. However, any communication must be secure and dependable due to the private nature of patient medical records. In this paper, we proposed an authentication method for the IoMT based on hyperelliptic curves and featuring dual signatures. The decreased key size of hyperelliptic curves makes the proposed scheme efficient. Furthermore, security validation analysis is performed with the help of the formal verification tool called Scyther, which shows that the proposed scheme is secure against several types of attacks. A comparison of the proposed scheme’s computational and communication expenses with those of existing schemes reveals its efficiency. Full article

The advantages of LoRaWAN over conventional networks (GSM, 4G, 5G) in terms of investment and operating costs have been proven for network coverage in urban and rural areas. However, the theoretical coverage compared to the reality on the ground and the quality of service (QoS) provided remain very relative and depend on several technical factors, subject to increased research. Several recent approaches and hardware specifications recommended adding gateways as a solution to improve the LoRaWAN QoS indicators, mainly for high-traffic situations. However, such a solution will not work in all real-life scenarios since many factors must be considered. This article presents a study of the factors impacting the LoRaWAN QoS in the case of the usage of multiple gateways by exploring different scenarios to show how the payload length impacts the whole network’s packet delivery ratio (PDR) and how it interacts when enhancing the GW number with and without confirmed traffic. Based on the simulation results, increasing the number of gateways can negatively impact the network’s ability to support higher payload packets, especially in a high-traffic scenario. More precisely, we can say that for a low number of GWs, it is more appropriate to use a high payload length since we can achieve a high PDR. Nevertheless, with a high number of GWs, it would be more appropriate to use a low payload length to achieve a good PDR. Similarly, our analyses show that increasing the number of gateways ensures a better PDR but with a significant packet loss at the gateways, which is synonymous with higher energy consumption.

Title: Synchronizing of local wifi network for layered sensor data transfer
Authors: Viktor Masalskyi; Andrius Dzedzickis; Urtė Samukaitė-Bubnienė; Vytautas Bučinskas
Affiliation: Vilnius Gediminas Technical University, Vilnius, Lithuania
Abstract: Data acquisition from independent sensor systems with further data fusion with remote data transfer embracing a problem of data stream synchronization. If the structure of the local network is simple - two microcontrollers-based systems collecting data from physical sensors, and the higher-level controller, transmitting data to PC, independent data acquisition can be synchronized via network request and therefore network became an active member in the data stream formation. The amount of data in each hub differs for every sensor type; therefore, synchronization has two layers of driving frequencies. The paper provides a successful attempt to solve local network connectivity-based sensor network solution. Research provides a logical solution, data acquisition scheme, network members identification and recognition, synchronization pattern, and possible limits of data flow. Experimental research of this technical solution brings results of the trials, and stability evaluation. At the end of the paper provided discussion and conclusions on obtained result are drawn.
