Abstract
Device-to-Device (D2D) communications and applications are expected to be a significant part of the Internet of Things (IoT). However, conventional network gateways reported in the literature are unable to provide sustainable solutions to the challenges posted by the massive amounts of D2D communications requests, especially in the context of the IoT for smart cities. In this paper, we present an admission control model for D2D communications. The model differentiates all D2D requests into delay-sensitive and delay-tolerant first, and then aggregates all delay-tolerant requests by routing them into one low-priority queue, aiming to decrease the number of requests from various number of devices in the IoT for smart cities. Also, an admission control algorithm is devised on the basis of this model to prevent access collision and to improve the quality of service. Performances are evaluated by the network calculus, numerical experiments, and simulations show that the proposed model is feasible and effective.
