如何为无线智慧停车城市网络选择相应的MAC协议?
How to Choose the Relevant MAC Protocol for Wireless Smart Parking Urban Networks?
摘要:
停车传感器网络正在全球范围内迅速部署,被视为智慧城市中首批实施的城市服务之一。为了提供最佳的网络性能,MAC协议应具有足够的自适应性,以满足交通强度和停车传感器的变化。本文研究了SmartSantander的重尾停车模型和空闲时间模型,并将该模型应用于四种不同的MAC协议,即基于竞争的、基于调度的以及它们的两种混合版本的仿真。结果表明,在收集一组停车传感器时,数据包到达间隔时间不再是重尾的,因此选择合适的MAC协议高度依赖于网络配置。此外,信息延迟是有界的业务和MAC参数,这是重要的标准,而及时的消息是必需的。
英文摘要:
Parking sensor network is rapidly deploying around the world and is regarded as one of the first implemented urban services in smart cities. To provide the best network performance, the MAC protocol shall be adaptive enough in order to satisfy the traffic intensity and variation of parking sensors. In this paper, we study the heavy-tailed parking and vacant time models from SmartSantander, and then we apply the traffic model in the simulation with four different kinds of MAC protocols, that is, contention-based, schedule-based and two hybrid versions of them. The result shows that the packet interarrival time is no longer heavy-tailed while collecting a group of parking sensors, and then choosing an appropriate MAC protocol highly depends on the network configuration. Also, the information delay is bounded by traffic and MAC parameters which are important criteria while the timely message is required.
