Abstract	A massive number of Internet-of-things (IoT) devices communicate with each other in a wireless network for applications like smart cities, smart classrooms and smart agriculture. The real-timeinformation exchange between these massive IoT nodes require connectivity and coverage. Advanced wireless techniques, cooperation among the communicating nodes and use of relays are fast emerging. But, increasing the communication reliability without adding to the energy or hardware overhead is the main challenge for these relay enabled massive IoT networks. Use of large number of relay nodes, antennas, radio-frequency (RF) transceiver chains in the cooperative communication enabled network increases the hardware complexity of the system. This paper addresses this challenge by proposing an energy efficient resource management model. The proposed resource optimization framework enables selection of optimal relay node and optimal number of antennas at the mobile node such that the system outage performance is improved. It is analysed that the resource optimization improves the outage probability by 12% at transmit power of 10dB at source node. The impact of increasing the number of node antennas on system ergodic capacity is also highlighted. The presented analysis finds applications in 6G enabled smart cities for seamless multimedia communication. As compared to existing systems with no resource optimization, the paper claims that incorporating resource optimization also results in huge energy savings at the mobile nodes. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022.
