| Abstract |
One of the most well-known uses of smart cities has been massive multimedia offerings. But the enormous demand for device-to-access point (D2A) communication has significantly increased the energy consumed and the greenhouse impact. As a result, energy-harvesting-based two-way access points (AP) and space shift keying (SSK) modulation are used to analyse the error performance of smart users in the smart city. Communication between smart users and a centralised AP is crucial in a smart metropolis. In this instance, energy harvesting at the two-way AP over the Saleh–Valenzuela channel has been taken into consideration using the simultaneous wireless information and power transmission (SWIPT) system. For smart users, SWIPT can remove the need for battery replacement or meet energy needs. In contrast, SSK modulation is a less complex method that does not need as many radio-frequency chains, inter-antenna synchronisation, or inter-channel interference for multiple-input-multiple-output transmission. Applying multi-user selection combining, smart sensors’ average bit error probability efficiency is derived in closed form. The numerical and simulation assessment results demonstrate how energy harvesting affects the system’s effectiveness. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024. |
