## 8 Conclusions and Discussion  
The proposed system adapts an integrated SWIPT and ABCS system to improve overall operational performance within an indoor environment. The main objective of the system was to develop a decision-making system that would effectively determine the choice between the two available options while maintaining better performance in terms of energy harvesting and information transmission. The integration of SWIPT and ABCS in a hybrid switch offers significant potential for energy efficiency in IoT networks deployed in warehouses. By leveraging both energy harvesting and passive communication techniques, the switch reduces dependency on external power sources and enhances operational autonomy. The specific selection of ABCS and SWIPT for the switch was also proven suitable due to the energy harvesting limitations and performance issues that arise when the source node moves away from the relay. The ideal option in cases where the EH probability is the lowest was shown to be ABCS; thus, the results show that the usage of this scheme within the switch allows for continued transmission during the worst conditions. Simulation results show that a mutual balance between power consumption and recharging of the system is achieved through the adaptation of the hybrid mechanism. The moderate to high SNR levels achieved by SWIPT ensure reliable data transmission, while the energy-efficient nature of ABCS provides a fallback option in challenging signal conditions. This dual approach enhances the overall robustness and reliability of data transmission in warehouse IoT networks. The initialization mechanism in the algorithm, based on aspects such as the hysteresis factor, minimum required threshold values, and trade-off between energy harvesting and QoS, allows the switch to adopt a more practical approach. Within the selected indoor setting, the system performance varied when the transmission distance from \(S\) to \(R\) increased. As seen from the simulation results, the proposed algorithm effectively switched between SWIPT and ABCS based on real-time parameters such as data rate requirements, energy harvesting capabilities, and SNR conditions. The switch was successful in ensuring that an appropriate amount of energy was harvested at \(R\), complying with the requirements of transmission in the \(R\)-\(D\) link, while making sure that the quality of service maintained at \(D\) was not compromised. The adjustment of transmission power at \(R\) to address the low signal quality demonstrated the capability of the switch to address the expected performance requirements. The main advantage of the system is the minimization of the requirement for a direct power source, or continuous battery replacement. The system, since it is capable of evaluating its own energy utilization and adjusting the transmission mode to suit the least energy-consuming methodology, offers a far longer battery life than any other energy harvesting-based or battery-powered relay. While the simulation results demonstrate the promising performance of the proposed hybrid switch, future research will focus on experimental validation in real-world environments. This practical implementation will provide insights into the power consumption characteristics of the switch and its performance under various environmental conditions. It would be further interesting to evaluate how the system performance would change in instances where the destination node changes position as well. Such an adaptation would further hinder the performance of the system, and requirements in improvements in the proposed algorithm may be called for, in order to address the Doppler effect and distance-related issues. While the addition of novel transmission methods to the system may be advantageous, the computational complexity of the switch would be too high, thereby requiring more power for decision-making. Thus, substituting the proposed transmission mechanisms with other suitable schemes may deem viable in certain use cases.
