In the past decade, we have witnessed the rapid development of the Internet of Things (IoT) and wireless sensor network (WSN). These technologies enable easy access and control of a verity forms of information and data from numerous number of smart devices, and give rise to many novel applications and research areas such as smart home, machine type communications (MTC), etc. In fact, IoT has been recognized as one of the key applications for 5G communications, and many efforts have been made to standardize the communication interface within the Third-Generation Partnership Project and using long-term evolution (LTE) bands to address the requirements of the IoT, eg, narrowband (NB) IoT [1]. The advantages of the IoT technology include improved coverage, support of massive number of devices, low latency, low device cost and power consumption, and optimized network architecture. However, the …
