the integration of the Internet of things (IoT) with 6G networks promises a huge potential for improvised industrial communication. A large number of low-power communication technologies is expected to be part of 6 G in industrial IoT for data collection, forwarding, and actuation. Industrial IoT (IIOT) requires deterministic network services, which can meet the demand for real-time services. Edge-based solutions can help 6G networks meet the requirements of real-time services demanding lower latency. this work aims to address such real-time demands with efficient use of radio resources using 6TiSCH (IPv6 over Time Slotted Channel Hopping (TSCH) mode). In this paper, we propose an edge-based downlink scheduling scheme for the 6TiSCH-based IIoT network named EDSN. EDSN leverages a computation and communication model using edge computing and 6TiSCH scheduling to minimize the overall network latency for downlink data traffic. It schedules actuation (downlink) signals based on the criticality of the received sensor data and the location of the actuators. EDSN analyzes traffic at the edge nodes and allocates a suitable downlink schedule to meet the application requirements of the edge controller. the scheme offers a fair mechanism for provisioning timely schedules for low-priority packets and significantly reduces downlink action times compared to the state-of-the-art. Our experimental results demonstrate that EDSN can effectively reduce response times and improve packet delivery ratios for priority traffic, making it a promising solution for IIoT applications that require low response times and reliable packet delivery. © 2024 ieee.

ieee international conference on Service-Oriented computing and Applications (SOCA)

作者： Horst Hellbrück Torsten Teubler Stefan Fischer Electrical Engineering and Computer Science Lübeck University of Applied Sciences Lübeck Germany Intitute of Telematics University of Lübeck Lübeck Germany

the goal of Service-Oriented Architectures (SOA) is to enable easy cooperation of a large number of computers and orchestration of services that are connected via a network. However, SOA for wireless sensor networks (WSN) and cyber-physical systems (CPS) is still a challenging task. Consequently, for design and development of large CPS like WSNs connected to clouds, SOA has not yet evolved as an integral technology. One of the limiting issues is service registration and discovery. In large CPS discovery of services is tedious, mostly due to the fact that services are often semantically bound to a region or an application function while SOA forces service endpoints to be based on addresses of nodes. Also, today, SOA technologies are not used for service composition within sensor nodes and between sensor nodes, and even worse, different methods exist for service access in a WSN and in the backend. therefore, service development differs largely in WSN and cloud. To overcome this limitation, we suggest a name-centric service architecture for cyber-physical systems. Our architecture is based on (a) using URNs instead of URLs to provide a service-centric architecture instead of service-or location-centric networking, (b) using the well-known CCNx protocol as a basis for our architecture which supports location and access transparency, and (c) employing CCN-WSN as the resource-efficient lightweight implementation for WSNs to build a name-based service bus for CPS. We evaluate the architecture by implementing an example application for facility management.

international conference on distributed computing systems Workshop

作者： Qian Zhao Yukikazu Nakamoto Zulfazli Hussin Graduate School of Applied Informatics University of Hyogo Kobe Japan

Although wireless sensor networks (WSNs) are becoming ubiquitous, the large amount of power consumed by wireless communications in transmitting sensing data from sensors to base stations or between sensor nodes themselves has become a critical problem. Since most sensor nodes are powered by batteries, we need to be more energy efficient to improve our ability to maintain them. As it is well-known that long communication distances between sensor nodes and base stations make WSNs consume more power as well as large amounts of sensing data, we propose a new energy-efficient wireless communication protocol called threshold controlled hierarchical routing (TCHR) to reduce the cost of wireless communication by reducing the communication distance in WSNs which the topology is considered closer to reality. We simulated our proposed protocol, and the simulation results demonstrated that the life of a WSN could be extended approximately 6 times longer than that with the direct data transmission protocol.

Traditionally, traffic management relies on several methods, including but not limited to signage, traffic signaling, and manual control. Traffic engineers analyze traffic patterns collected through various sensors and use their expertise to manage traffic flow. While traditional traffic management methods have been adequate to some extent, they often need to be improved in handling traffic's complexity and dynamic nature in modern urban environments. the usage of advanced technologies in autonomous traffic volume is adapted to address the limitation. Traffic data are complex, and mathematical models relying upon simplified assumptions often must be revised to represent and analyze the complexity. With the revival of neural networks and large-scale datasets, deep learning-based solutions can be adapted to handle real-world traffic scenarios. Since neural networks can capture complex, non-linear relationships in traffic data, they can be utilized for intricate traffic patterns and dependencies that may be challenging for simple mathematical or regression models. We present a Deep Learning approach for accurately predicting traffic volume in Porto, Portugal. the proposed model leverages an extensive dataset encompassing historical traffic volume data from diverse sensors and monitoring systems. By harnessing the power of Recurrent Neural Networks (RNNs), the proposed model effectively captures temporal dependencies and generates precise forecasts for future traffic volume. the proposed approach surpasses previous methodologies in the same dataset, outperforming traditional time series models in different evaluation metrics. these findings demonstrate the practical potential of deep learning-based models in complex urban environments and offer a way to utilize sensor data. the proposed approach can adapt to changing traffic conditions and evolving patterns with infrequent training, making them suitable for dynamic environments. © 2023 ieee.

the availability of inexpensive CMOS cameras and microphones that can ubiquitously capture multimedia content from the environment is fostering the development of Wireless Multimedia sensor Networks (WMSNs), i.e., distributed systems of wirelessly networked devices that can retrieve video and audio streams, still images, and scalar sensor data. WMSNs require the sensor network paradigm to be re-thought in view of the need for mechanisms to deliver multimedia content with a pre-defined level of quality of service (QoS). A new rate control scheme for WMSNs is introduced in this paper with a two-fold objective: i) maximize the video quality of each individual video stream; ii) maintain fairness in video quality between different video streams. the rate control scheme is based on both analytical and empirical models and consists of a new cross-layer control algorithm that jointly regulates the end-to-end data rate, the video quality, and the strength of the channel coding at the physical layer. the end-to-end data rate is regulated to avoid congestion while maintaining fairness in the domain of video quality rather than data rate. Once the end-to-end data rate has been determined, the sender adjusts the video encoder rate and the channel encoder rate based on the overall rate and the current channel quality, with the objective of minimizing the distortion of the received video. Simulations show that the proposed algorithm considerably improves the received video quality without sacrificing fairness.

Self-Protection for Wireless sensor Networks

Self-Protection for Wireless Sensor Networks

Wireless sensor networks have recently been suggested for many surveillance applications such as object monitoring, path protection, or area coverage. Since the sensors themselves are important and critical objects in the network, a natural question is whether they need certain level of protection, so as to resist the attacks targeting on them directly. If this is necessary, then who should provide this protection, and how it can be achieved? We refer to the above problem as self-protection, as we believe the sensors themselves are the best (and often the only) candidate to provide such protection. In this papel; we for the jirst time present a formal study on the selfprotection problem in wireless sensor networks. We show that, if we simply focus on the quality ofjield or object covering, the sensors might not necessarily be self-protected, which in turn makes the system vulnerable. We then investigate dzreerent forms of self-pmtections, and show that the problems are generally NP-complete. We develop eficient approximation algorithms for centrally-controlled sensors. We then extend the algorithms to filly distributed implementation, and introduce a smart sleep-scheduling algorithm that minimize the energy consumption.

While symmetric-key schemes are efficient in processing time for sensor networks, they generally require complicated key management, which may introduce large memory and communication overhead. On the contrary, public-key based schemes have simple and clean key management, but cost more computational time. the recent progress of elliptic curve cryptography (ECC) implementation on sensors motivates us to design a public-key scheme and compare its performance with the symmetric-key counterparts. this paper builds the user access control on commercial off-the-shelf sensor devices as a case study to show that the public-key scheme can be more advantageous in terms of the memory usage, message complexity, and security resilience. Meanwhile, our work also provides insights in integrating and designing public-key based security protocols for sensor networks.

Some sensor network applications involve an aerial deployment of many sensor nodes over a particular area of interest. In this context, current range-free localization proposals, based on an iterative refinement and exchange of node estimations, are not directly applicable, because they introduce a high traffic overhead. In this paper, we propose to control this overhead by means of avoiding the transmission of certain localization packets. the criterion applied by this new localization technique to filter packets is based on the amount of improvement shown after updating an estimation and the time from the last transmission. We also tune this filter in order to find an optimal trade-off between the benefit in traffic and the penalty in time.

Recently, surveillance systems for public safety have become more intelligent through context awareness. Basically, traditional surveillance systems require power and networking infrastructure to operate the system and to transmit recorded data. these requirements increase the cost of system installation and maintenance. this paper proposes a wireless video sensor network platform for public safety. the proposed platform includes a high-resolution surveillance system, wireless networking platform, and smart functions. Even though the platform captures high-resolution images and transmits them via high speed wireless networks, such as Wi-Fi Mesh (ieee 802.11s), the system and the network are energy efficient by decomposing the system and the network into two systems: low-power and high-performance. the proposed system and platform can be used for wireless back born networks and for infrastructure of wireless sensor networks. this paper also deals with applications of the proposed system and platform.
