Abstract
The technological breakthrough of the Internet of Things (IoT) drives the emergence of a wide scope of smart IoT solutions in different domains. Advancing the different technological aspects of these solutions requires effective IoT implementations and experimentations. This is widely addressed following low-cost and scalable methods such as analytical modeling and simulation. However, such methods are limited in capturing physical characteristics and network conditions in a realistic manner. Therefore, this paper presents an innovative IoT testbed system which facilitates practical experimentation of different IoT solutions in an effective environment. The testbed design was developed towards a general-purpose multidimensional support of different IoT properties including sensing, communication, gateway, energy management, data processing, and security. The implementation of the testbed was realized based on integrating a set of robust hardware components and developing a number of software modules. To illustrate its effectiveness, the testbed was utilized to experiment with energy efficiency of selected IoT communication technologies. This resulted in lower energy consumption using the Bluetooth Low Energy (BLE) technology compared to the Zigbee and 6LoWPAN technologies. A further evaluation study of the system was carried out following the Technology Acceptance Model (TAM). As the study results indicated, the system provides a simple yet efficient platform for conducting practical IoT experiments. It also had positive impact on users’ behavior and attitude toward IoT experimentation.
