Real-Time data dissemination and analytics platform for challenging IoT environments

Abstract

The advent of Internet-of-Things (IoT) applications, such as environmental monitoring, smart cities, and home automation, has taken the IoT concept from hype to reality at a massive scale. However, more mission-critical application areas such as energy, security and health care do not only demand low-power connectivity, but also highly reliable and guaranteed performance. While fulfilling these requirements under controlled conditions such as urban and indoor environments is relatively trivial, tackling the same obstacles in a more challenging and dynamic setting is significantly more complicated. In environments where infrastructure is sparse, such as rural or remote areas, specialized infrastructure-less ad-hoc solutions are needed, which provide long-range multi-hop connectivity to remote sensors and actuators. In this paper we propose a new general-purpose IoT platform based on a combination of Low-power Wireless Personal Area Network (LoWPAN) and multi-hop Wireless Sensor Network (WSN) technology. It supports reliable and guaranteed realtime data dissemination and analysis, as well as actuator control, in dynamic and challenging infrastructure-less environments. In this paper, we present the IoT platform architecture and an initial hard-and software prototype. Moreover, a use case based on realtime monitoring and training adaptation for cyclists is presented. Based on this case study, evaluation results are presented that show the ability of the proposed platform to operate under challenging and dynamic conditions.

Combining IoT Deployment and Data Visualization: experiences within campus maintenance use-case

“…Several surveys identify different frameworks for IoTbased applications [8], [9]. Mostly, IoT frameworks are delivered as middleware solutions including device management, platform portability, context-awareness, security, and privacy properties.…”

“…Finally, Al-Fuqaha et al [8] provide technical details of different IoT architectures and corresponding prototypes that deliver desired services. Daneels et al [9] propose IoT platform which can serve both Low-power Wireless Personal Area Network and multi-hop Wireless Sensor Network technology. Initial hardware and software prototype for this IoT architecture was presented.…”

“…Physical layer is formed by sensor nodes and the IoT gateways. The potential solutions for IoT on the physical layer ranges from, e.g., LPWAN, ZigBee, Wi-Fi, Bluetooth to LTE-A and 5G-MTC [8], [9]. However, LPWAN is being the dominant form of long-range wireless network for IoT devices.…”

A Key 6G Challenge and Opportunity - Connecting the Remaining 4 Billions: A Survey on Rural Connectivity

“…IoT devices would relay their data in a multihop fashion until reaching a gateway that is connected to the internet, e.g., via GPRS or 3G. In [94], range extension in rural areas was performed by using IEEE 802.15.4 with multihop transmission in the 868 MHz band to extend the hop range, along with time slotted channel hopping to increase robustness. In [95], to ensure k-th order receive diversity of IoT measurements in an LPWAN, the placement of gateways is investigated, such that the transmission of each sensor is received by k gateways.…”

Exploiting Offloading in IoT-Based Microfog: Experiments with Face Recognition and Fall Detection

“…Distributed processing in an infrastructure based on the architectural limitations of the environment devices has not been adequately addressed. The authors in [30] describe an IoT platform to ensure reliable data dissemination and analysis in the communication in rural and remote areas, where the wireless infrastructure is sparse. Thus, the authors handle with the connectivity problem by using long-range multihops between sensors and actuators.…”
