Scalable IoT Platform for Heterogeneous Devices in Smart Environments

Abstract

The Internet of Things (IoT) is envisioned as a ubiquitous computing infrastructure in which everything becomes connected, enabling gigantic information exchange among Things and people. These connected smart Things generate an enormous amount of data which need to be efficiently managed to form a unified global IoT. Unfortunately, due to the lack of acceptable open standards, communication protocols, and support for device/service discovery, the recent IoT deployments in smart environments (e.g., smart home, smart building, smart city) are posing imperative challenges related to interoperability, discovery, and the configuration of deployed objects, since the number of objects is expected to grow over time. Therefore, it is of utmost importance to provide open and scalable solutions for the discovery of devices (i.e., Things), their configuration, and data management. This paper introduces an open and scalable IoT platform by adopting the modular characteristics of edge computing for smart environments. This paper: (i) performs a systematic literature review of IoT-based infrastructures and analyzes the scalability requirements; (ii) proposes a layered IoT platform for smart environments that fosters heterogeneity, interoperability, discovery, and scalability; and (iii) demonstrates the applicability of the proposed solution by relying on a comprehensive study of a Väre smart building use case at Aalto University.

QoS‐aware IoT networks and protocols: A comprehensive survey

“…In the literature, mainly cloud/fog/edge computing-based solutions have been proposed to tackle scalability issues; however, there is a necessity for more modular approaches in edge computing-based smart environments. 173 Security and QoS are inevitably intertwined 38 as the IoT systems should be capable of differentiating between malicious and legitimate traffic in order to maintain their QoS, and this is particularly challenging in big IoT applications. Compromised security may lead to an overburdened network, high response times and end-to-end delays, inefficient resource utilization, etc.…”

Fog Computing Platforms for Smart City Applications: A Survey

“…Interoperability between platforms -According to [34], to overcome vertical silos, it is necessary to provide standardized communication protocols and semantic data models that are open and should not change from one platform to another. There are several beneits to platform integration, such as enabling services that use information from diferent domains and sharing of resources, thus potentially increasing the return on investment (ROI) for service providers.…”

Home Monitoring of Pets Based on AIoT

“…When the sensor detects that the indoor temperature is lower than 16°C, the system turns on the heater. If the indoor humidity is above 60%, the system turns on the dehumidifier, the operation of which is reassessed every 30 min to ensure optimal energy use [25]. 5a shows a flowchart of illuminance-sensing control.…”
