An Enhanced Random Access Algorithm Based on the Clustering-Reuse Preamble Allocation in NB-IoT System

An Enhanced Random Access Algorithm Based on the Clustering-Reuse Preamble Allocation in NB-IoT System

As a new wireless access technology, Narrow Band IoT (NB-IoT) enables low-power wide-area coverage services and can be applied to many domains. Emerging applications such as smart traffic, shared bicycles and shared cars have put forward more stringent requirements for connectivity. In order to get...
