Abstract

In future remote healthcare monitoring system, it is necessary to constantly monitor the patients physiological parameters. For example, a pregnant woman parameters such as blood pressure and heart rate of the woman and heart rate and movements of fetal to control their health condition. To support the high-intensity and short-lived demands of these emerging applications, Narrowband Internet of Things (NB-IoT) is a promising technology that provides long-range communications at a low data rate for sensors with reduced device processing complexity and long battery lifetime. This paper aims to investigate the realistic performance of NBIoT in terms of effective throughput, patient served per cell and latency in healthcare monitoring system with both in-band and stand-alone deployment.

5. Conclusion

In this paper, we have presented a detailed application-specific performance analysis of NB-IoT for healthcare monitoring system with both SND and MND. From the conducted analysis, it can be seen that with MND design significant gain in throughput and number of patients per cell is observed at the cost of increased delay. This is due to the reduction in overhead of control information transmission. From the results, it is also concluded that to provide a suitable solution for the different use case scenarios, one has to jointly optimize the required throughput, delay and device density. As future work, based on the results of this work, we will be able to evaluate different strategies for resource management in NB-IoT systems for specific use case scenarios.
