Special Issue Information

Dear Colleagues,

Wireless technologies enable seamless integration of communication, control, and computation. Data transmission, sensing, control, and actuation applications are converging to the Internet of Things (IoT), with billions of wireless devices deployed to intelligently interconnect people, objects, and machines. New applications such as tactile Internet, remote surgery, augmented or virtual reality (AR/VR), and autonomous driving, where the mission criticality is a common characteristic, are posing more stringent requirements on reliability, delay, and resilience.

Standards organizations, such as the 3rd Generation Partnership Project (3GPP), the Bluetooth Special Interest Group (SIG), the Institute of Electrical and Electronics Engineers (IEEE), and the Internet Engineering Task Force (IETF), are extensively working on wireless protocol enhancements to support these demands. Accurate and computationally affordable techniques for protocol modeling and optimization are then fundamental to guarantee the integration of large-scale networks with a variety of potentially competing service requirements over the same physical medium. Energy-efficient operations, adaptability to heterogeneous and strict requirements, and interoperability represent challenging aspects that need to be addressed. In this context, stochastic network optimization and machine learning techniques are powerful tools that can be used in combination with currently used analytical approaches.

This Special Issue targets scientific contributions on wireless sensor/actuator networks and systems (WSANs) addressing heterogeneous and strict communication requirements (hopefully in combination), such as reliability and robustness, timeliness and real-time, scalability, mobility, security and privacy, and energy efficiency and sustainability. We are interested in papers dealing with innovative solutions that have been sufficiently evaluated through analytical, simulation or experimental models (hopefully in combination). Extensions to previously published works are accepted, but it needs to be clearly stated in the submission, and the new contribution needs to be clear.

Topics of interest are:

  • Communication standards and technologies for wireless sensor and actuator networks, e.g. IEEE 802.11, WiFi, IEEE 802.15.4, ZigBee, Bluetooth Low Energy, NB-IoT, RFID, and their integration/interoperability;
  • System architectures and communication infrastructures to fulfill strict performance requirements; scalability;
  • Cross-layer protocol design: MAC and PHY interactions, wireless network integration, and interoperability with wired systems;
  • Reliability and robustness: improving communication error detection/correction, hardware robustness, systems reliability in general;
  • Timeliness and real-time operations: improving the timing behavior and reducing end-to-end communication delays;
  • Security and privacy: new mechanisms to grant adequate levels of security/privacy without jeopardizing energy and time;
  • Mobility: mechanisms to support mobile devices in a seamless and transparent way, i.e., still respecting the overall performance requirements;
  • Energy efficiency and harvesting: improving lifetime, e.g., through optimized communications scheduling or duty-cycling and trade-offs between energy and performance;
  • Real-case applications, such as in building and industrial automation, vehicular networks or security/surveillance.

Product counterfeiting is a continuous problem in industry. Recently, an anti-counterfeiting protocol to address this issue via radio-frequency identification (RFID) technology was proposed by researchers. Yet, the use case of reselling the same product has not been fully addressed which might cause serious problems for the exciting and proposed schemes and transactions. This paper proposes an extended RFID-based anti-counterfeiting protocol to address the use case of the original buyer reselling the same item to a second buyer. We will follow the proposed extended scheme with a formal security analysis to prove that the proposed protocol is secure and immune against most known security attacks. Full article

With the latest standard releases, Bluetooth technology is becoming more and more relevant for building and industrial automation. At the same time, Bluetooth is now becoming fundamental for contact tracing applications, to support monitoring and containment of the COVID-19 pandemic. Critical facilities such as nursing homes and hospitals have been severely exposed to the pandemic, but the currently available short-range wireless technology still faces the fundamental limits of proximity accuracy, battery lifetime, and privacy in those complex indoor environments. The aim of this paper is to investigate effective ways of building an architecture with heterogeneous devices to support contact tracing in critical scenarios such as healthcare facilities, while meeting the required level of accuracy and privacy. A framework based on standard Bluetooth mesh networking technology is proposed, and the research challenges are discussed. Full article

In the design of multi-loop Networked Control Systems (NCSs), wherein each control system is characterized by heterogeneous dynamics and associated with a certain set of timing specifications, appropriate metrics need to be employed for the synthesis of control and networking policies to efficiently respond to the requirements of each control loop. The majority of the design approaches for sampling, scheduling, and control policies include either time-based or event-based metrics to perform pertinent actions in response to the changes of the parameters of interest. We specifically focus in this article on Age-of-Information (AoI) as a recently-developed time-based metric and threshold-based triggering function as a generic Event-Triggered (ET) metric. We consider multiple heterogeneous stochastic linear control systems that close their feedback loops over a shared communication network. We investigate the co-design across the NCS and discuss the pros and cons with the AoI and ET approaches in terms of asymptotic control performance measured by Linear-Quadratic Gaussian (LQG) cost functions. In particular, sampling and scheduling policies combining AoI and stochastic ET metrics are proposed. It is argued that pure AoI functions that generate decision variables solely upon minimizing the average age irrespective of control systems dynamics may not be able to improve the overall NCS performance even compared with purely randomized policies. Our theoretical analysis is validated through several simulation scenarios. Full article

Research related to Wireless Body Area Networks (WBAN) has recently gained more attention due to its application in enabling smart healthcare systems. A WBAN consists of several sensing nodes and a dedicated coordinator. The distributed nodes communicate with the coordinator by accessing the physical communication channel in a randomly distributed fashion. Random channel access may cause frame re-transmission of corrupted frames due to frame collisions. As a result of that, there will be degradation in the WBAN throughput, an increase in delay, and a waste of node energy. Nodes within a WBAN can be classified using specific user priorities allowing for prioritized communication to reduce possible frame collisions. To improve the performance and energy efficiency, this work aims to reduce collisions among nodes that belong to the same users’ priority (homogeneous collisions) and collisions among nodes of different users’ priorities (heterogeneous collisions). Homogeneous collisions can be reduced by scaling the minimum Contention Window (CW) among nodes within the same user priority, whereas heterogeneous collisions can be reduced by allowing higher user priority nodes to transmit while lower user priority nodes enter into a backoff state. This paper presents an analytical model and extensive simulations to show the enhanced performance of the proposed collision avoidance mechanism. The results show that the throughput and node energy efficiency is improved by a factor of three and two times, respectively. Full article

Water covers a greater part of the Earth’s surface. However, little knowledge has been achieved regarding the underwater world as most parts of it remain unexplored. Oceans, including other water bodies, hold substantial natural resources and also the aquatic lives. These are mostly undiscovered and unknown due to the unsuited and hazardous underwater environments for the human. This inspires the unmanned exploration of these dicey environments. Neither unmanned exploration nor the distant real-time monitoring is possible without deploying Underwater Wireless Sensor Network (UWSN). Consequently, UWSN has drawn the interests of the researchers recently. This vast underwater world is possible to be monitored remotely from a distant location with much ease and less risk. The UWSN is required to be deployed over the volume of the water body to monitor and surveil. For vast water bodies like oceans, rivers and large lakes, data is collected from the different heights/depths of the water level which is then delivered to the surface sinks. Unlike terrestrial communication and radio waves, conventional mediums do not serve the purpose of underwater communication due to their high attenuation and low underwater-transmission range. Instead, an acoustic medium is able to transmit data in underwater more efficiently and reliably in comparison to other mediums. To transmit and relay the data reliably from the bottom of the sea to the sinks at the surface, multi-hop communication is utilized with different schemes. For seabed to surface sink communication, leading researchers proposed different routing protocols. The goal of these routing protocols is to make underwater communications more reliable, energy-efficient and delay efficient. This paper surveys the advancement of some of the routing protocols which eventually helps in finding the most efficient routing protocol and some recent applications for the UWSN. This work also summarizes the remaining challenging issues and the future trends of those considered routing protocols. This survey encourages further research efforts to improve the routing protocols of UWSN for enhanced underwater monitoring and exploration. Full article
