A Large-scale Access Scheme for Internet of Things Based on Distributed Queuing

Internet of Things will be one of the most important application scenarios of the future 5G technology. However, the competition solution mechanism of the traditional cellular network cannot satisfy the large-scale access demand. Under the traditional scheme, when there are too many devices switched in the stability of the whole system will be impaired, thus causing serious congestion and making it hard to guarantee the service quality. Concerning the above problems, this paper proposes a large-scale access scheme for Internet of Things that is based on the distributed column and the tree-splitting algorithm. Simulation results suggest that, when a large number of devices have the request of access, the access scheme proposed by this paper can reasonably balance the access time delay, access success rate, and other indexes.
