机器对机器(M2M)通信和应用预计将成为物联网(IoT)的重要组成部分。然而,文献中报道的传统网络网关无法为大量M2M通信请求所带来的挑战提供可持续的解决方案,特别是在智能城市的物联网背景下。在本文中,我们提出了一个准入控制模型的M2M通信。该模型首先将所有M2M请求区分为延迟敏感和延迟容忍,然后通过将所有延迟容忍请求路由到一个低优先级队列中来聚合所有延迟容忍请求,旨在减少从各种设备到物联网接入点的请求数量。在此模型的基础上设计了一种接纳控制算法,以防止接入冲突,提高服务质量。通过网络演算、数值实验和仿真实验,验证了该模型的可行性和有效性。
Machine-to-machine (M2M) 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 M2M communications requests, especially in the context of the IoT for smart cities. In this paper, we present an admission control model for M2M communications. The model differentiates all M2M 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 reduce the number of requests from various devices to the access point 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. Performance evaluations by network calculus, numerical experiments, and simulations show that the proposed model is feasible and effective.
