Abstract
Consumer electronics has witnessed rapid proliferation owing to the tremendous adoption of Internet-of-Things (IoT) technologies. The growing interaction between cyber world and the physical world demands intelligent and connected consumer products for ubiquitous information exchange. But the vulnerability to lack of coordinated connections, energy aware network solutions and regulated technology integrations is the main challenge. Thus it is very important to have new and sustainable support paradigm for next generation (next-gen) IoT based consumer electronics. This paper presents a robust resource control mechanism for consumer electronics based IoT network that offers communication support and reduced energy overhead. An intelligent reflecting surface (IRS) aided network model is proposed in which the consumer nodes or devices connect to the access points using various multiple IRSs. To foster the connected devices network in sustainable manner, resource control algorithm is proposed which enables the selection of optimal IRS against all IRSs. The performance of the network is evaluated for achievable sum rate for different transmit powers, different IRS phase shifts and number of IRS passive elements. It is observed that introduction of resource control scheme improves the achievable sum rate of the system by 9% using IRS with more reflecting elements with optimal phase shifts. Further, the energy efficiency analysis is carried out by proposing a power consumption model taking the power consumed by the circuit components into account. The proposed resource control enables the network model to attain maximum energy efficiency at lower signal-to-noise ratio (SNR) regime.
