Low-Complexity Data Collection Scheme for UAV Sink Nodes in Cellular IoT Networks

A Resource Allocation Scheme for Packet Delay Minimization in Multi-Tier Cellular-Based IoT Networks

“…IoT technologies, such as smart cities, vehicular communication, autonomous driving, and remote health care, demand a high amount of data traffic for wireless networks and are growing explosively [2]. In this context, providing reliable wireless access for the massive IoT devices and the diversification of data traffic is essential to the realization of 5G IoT networks and has attracted considerable attention from academia and industry [2,4]. Cellular-based IoT networks are considered the most promising potential solution to provide last-mile connectivity for IoT devices due to their cost-effective deployments and guaranteed services, such as high scalability, diversity, and security, which do not need massive additional infrastructure deployments and significant changes in current cellular networks [2,5].…”

“…In IoT networks, a broad range of IoT services are enabled by massive amounts of IoT devices to monitor environmental factors such as temperature and humidity [4,7]. In this case, IoT devices need to process different data traffic streams for various receivers, where each traffic stream has different performance metrics, such as delay, throughput, or AoI, in characterizing the timeliness [1,2,4]. Then, there is an unavoidable need for designing innovative data-collection mechanisms for cellular-based IoT networks to enhance efficiency and scalability [7].…”

“…Then, a series of works utilized the results of [8] by characterizing the temporal mean of AoI or other freshness-related metrics for various variations in queuing models. In [4], the authors applied the concept of AoI to measure the freshness of information at the BSs regarding the random processes monitored by IoT devices, while [1] studied the AoI of K-tier cellular-based IoT networks while considering weighted path loss association policy and fractional power control strategy. However, artificial designs, like utilizing timing advance (TA) information to avoid collisions, can result in unfairness, which is not considered in most existing studies.…”

“…T HE Internet of Things (IoT) is a vital technology of contemporary wireless communication systems [1], and has been widely applied in diverse fields, such as intelligent cities [2], smart homes [3], and smart agriculture [4]. Among them, the IoT in agriculture has developed rapidly and plays a key role in modern agricultural production.…”

“…Among them, the IoT in agriculture has developed rapidly and plays a key role in modern agricultural production. Furthermore, the rapid implement of IoT tightly depends on the development of wireless sensors networks (WSNs) [1], which are made up of massive sensors with the abilities of sensing, processing and communication. However, due to the constraints of technology and finance, sensors are battery-powered devices, and their limited lifetime has a great effect on the performance improvements and perception ability in WSNs, which results in a lot of researches devoted to increasing the lifetime of sensors [5], [6].…”
