Special Issue Information

Dear Colleagues,

Today, there are 37 megacities with more than 10 million citizens and 220 big cities with more than 1 million citizens. Therefore, efficient and effective management and control of traffic congestion, energy consumption, waste, and pollution are resulting in severe economic and social implications for the citizens of those cities. The recent technology convergence of Internet of Things (IoT)/sensor devices, their networks, and the augmented reality/virtual reality (AR/VR) using them has been creating new demands and opportunities to deal with those problems in smart cities. In particular, the growing number of heterogeneous IoT, sensor, and actuator devices in addition to the demanding wired/wireless communications in their integrated systems impose several challenges as both traditional research problems and new innovative research issues related to smart cities. Moreover, human and non-human systems based on recent AR/VR technology interact consistently and allow each to achieve a set of non-trivial smart interaction in smart cities. This Special Issue aims to gather recent advanced technologies and applications that address intelligent IoT/sensor devices’ low latency networking, context-aware interaction, energy efficiency, resource management, security, human–robot interaction, assistive technology and robots, application development, and the integration of multiple systems that support smart interaction in smart cities. High-quality, original research papers covering key issues and topics of smart cities will be considered for publication. Accordingly, this Special Issue will bring together researchers in both industry and academia in highlighting the appropriate current and future directions in the areas.

Topics for this Special Issue include but are not limited to:

* Human-centric context management for interaction in smart cities

* IoT/sensor management for advanced (mobile) ubiquitous applications for smart cities

* IoT/sensor applications and middleware support for smart cities

* Smart low latency and real-time IoT/sensor communication

* IoT/sensor energy efficiency

* Distributed sensing, actuation, control, and coordination

* Network resilience, fault-tolerance, and reliability

* Privacy, security, and trust management of IoT/sensor devices

* IoT-based blockchain technology and applications for smart cities

* Intelligent resource management for smart cities

* Functional computation and data aggregation

* Distributed algorithms and intelligent network optimization for smart cities

* Measurements from experimental systems for smart cities

* Prototypes, testbeds, and real-world deployments of intelligent systems for smart cities

* Smart AR/VR interaction for smart cities

* Immersive haptic interaction for smart cities

* Tactile internet for smart cities

* AR/VR devices and technologies integrated with IoT/sensors for smart cities

* Reasoning and learning techniques for human-centric interaction in smart cities

Freehand exercises help improve physical fitness without any requirements for devices or places. Existing fitness assistant systems are typically restricted to wearable devices or exercising at specific positions, compromising the ubiquitous availability of freehand exercises. In this paper, we develop MobiFit, a contactless freehand exercise assistant using just one cellular signal receiver placed on the ground. MobiFit passively monitors the ubiquitous cellular signals sent by the base station, which frees users from the space constraints and deployment overheads and provides accurate repetition counting, exercise type recognition and workout quality assessment without any attachments to the human body. The design of MobiFit faces new challenges of the uncertainties not only on cellular signal payloads but also on signal propagations because the sender (base station) is beyond the control of MobiFit and located far away. To tackle these challenges, we conducted experimental studies to observe the received cellular signal sequence during freehand exercises. Based on the observations, we constructed the analytic model of the received signals. Guided by the insights derived from the analytic model, MobiFit segments out every repetition and rest interval from one exercise session through spectrogram analysis and extracts low-frequency features from each repetition for type recognition. Extensive experiments were conducted in both indoor and outdoor environments, which collected 22,960 exercise repetitions performed by ten volunteers over six months. The results confirm that MobiFit achieves high counting accuracy of 98.6%, high recognition accuracy of 94.1% and low repetition duration estimation error within 0.3 s. Besides, the experiments show that MobiFit works both indoors and outdoors and supports multiple users exercising together. Full article
