Abstract
In Internet of Things (IoT), narrow band IoT (NB-IoT) based on cellular networks is expected to play an important role for providing low power, wide area services, supporting deep indoor deployment, massive devices in one cell. However, massive access requests in resource-finite situation may bring out severe congestion and delay. To alleviate congestion and delay problems, we propose a delay-aware dynamic barring scheme in this paper. According to different delay requirements, the proposed scheme can ensure higher priority for delay-sensitive services. Compared with standard access class barring (ACB) scheme, both success probability and delay for delay-sensitive devices can be improved significantly, with several sacrifice on delay-tolerant performance.
