Architectures for Applications and Services Provisioning in Internet of Things

物联网（IoT）使无线传感器和执行器等设备能够在很少或没有人为干预的情况下相互连接和通信。据保守估计，到2020年，这些连接设备的数量将达到惊人的200亿。 潜在的应用和服务有很多。然而，提供这些应用程序和服务是相当具有挑战性的。需要健全和创新的架构。这些挑战包括成本效率、体验质量（QoE）和敏捷性。云计算、雾计算、网络功能虚拟化（NFV）和软件定义网络（SDN）等新兴技术可以帮助解决这些问题。这项拟议的研究是我在过去6年中用我的发现资助所做工作的延续，这是由我在过去2年中获得的两项思科合作研究计划资助所补充的。它旨在提供具有成本效益和敏捷的应用程序和服务配置架构，为最终用户提供高质量的体验（QoE）。我们的目标是为物联网中的应用和服务提供成熟和完全集成的解决方案。这些解决方案将集成云架构以实现成本效益，雾架构以实现QoE，NFV/SDN架构以实现敏捷性。对于每一个架构，我们将研究组件，接口和伴随的算法。 我们将提出专注于传感的架构和专注于驱动的架构，然后将它们用作成熟的物联网解决方案的支柱。 根据IDC的预测，到2018年，加拿大物联网（IoT）市场的价值将超过65亿美元，并将在接下来的几年中继续以强劲的速度增长。这项研究将有助于增长。*****

Internet of Things (IoT) enables devices such as wireless sensors and actuators to be connected and to communicate with each other, with little or no human intervention. According to conservative estimates, the tally of these connected devices will reach the staggering number of 20 billion in 2020. Potential applications and services are numerous. However provisioning these applications and services is quite challenging. Sound and innovative architectures are required. The challenges include cost efficiency, Quality of Experience (QoE), and agility. Emerging technologies such as cloud computing, fog computing, network function virtualization (NFV), and Software Defined Network (SDN) can help in tackling them. This proposed research is a continuation of the work I have done the last 6 years with my discovery grant which was complemented by two CISCO collaborative research initiatives grants I was awarded the last 2 years. It aims at cost efficient and agile applications and services provisioning architectures which deliver high Quality of Experience (QoE) to end-users. We aim at full-fledged and fully integrated solutions to applications and services provisioning in IoT. These solutions will integrate cloud architectures for cost efficiency, fog architectures for QoE and NFV/SDN architectures for agility. For each one of the architectures we will research components, interfaces and accompanying algorithms. We will propose architectures which focus on sensing and architectures which focus on actuation, then use them as the pillars of the full-fledged IoT solutions. According to IDC forecasts, the Canadian Internet of Things (IoT) market will be worth more than $6.5 billion by 2018 and will continue growing at a vigorous pace the following years. This proposed research will contribute to the growth. *****
