A Survey of Dynamic Bandwidth Allocation to Enhance Quality of Service in Internet of Things

Internet of Things (IoT) is one of the most popular buzzwords in the twenty-first century. The Internet of Things (IoT) is flourishing, facilitating, and improving people’s lives all over the world as a result of the expanding technological breakthroughs. IoT-related ideas like augmented reality, a smarter environment, smarter healthcare, and self-driving automobiles have permeated every aspect of our daily lives. There is a huge market of IoT devices especially in the communication networks, several reports are informing. Some nations independently expand about two thirds of these IoT devices. Numerous IoT issues might be caused by low computing power and broadband availability. A few of them are security, heterogeneity, low power, and other issues. Considering this, it is a challenging issue to distribute the bandwidth to billions of IoT devices using the current infrastructure. In this study, we first introduce the IoT and the various industries in which it is used, then we analyze several methods for bandwidth allocation. Finally, it has been observed that more sophisticated bandwidth control techniques are required to offer Quality of Service to all connected IoT devices.
