Next generation Internet, commonly referred to as the Internet of Things (IoT), has the potential to improve our daily lives significantly. The IoT will allow global interconnection of heterogeneous smart objects through mobile-based machine-to-machine (M2M) communications. The list of smart objects includes smartphones, smart cars, homes and cities and IoT is expected to find applications in transportation, healthcare, smart environment (home, office, plant) and social networks. IoT presents many new challenges in the scale of the number of devices to be connected, communications, robustness, security and big data. It is expected that the number of devices to be deployed in IoT to reach trillions. Most of the mobile devices to be connected have limited processing power, storage and battery life. Cloud computing will provide the additional computing power and storage needed by mobile devices. Large amount of raw data will be continuously collected through real-time sensors and stored in clouds for analysis and inference, which will create new knowledge. ***Wireless communications is expected to play a critical role in IoT as it is to provide access to mobile users, sensor networking etc. The demand for higher data rates and massive number of wireless devices with differing quality of service (QoS) requirements to be connected to the Internet is creating new challenges for next generation (5G) wireless networks. It is envisioned that 5G networks will meet these demands through very dense deployments, moving into millimeter wavelengths spectrum and centralized processing. It is expected that 5G technology will result in hierarchical and heterogeneous network architecture (HetNet). HetNet will have multi-tier cell architecture with cell sizes ranging from macro to small cells. As networks become denser, interference management will become more critical due to multi-cell interference. As a result, centralized control of radio access networks through software-defined-network (SDN) management has been proposed for efficient resource allocation and interference management. ***A very important goal of this research proposal is development and optimization of network architectures and communication protocols for 5G networks. We will consider optimization of resource allocation, energy efficiency and QoS provisioning in 5G networks that maximizes network utility. We will develop optimization tools for design of the networks as well as heuristic algorithms for online implementation. We will also consider optimization of resource allocation in cloud computing centers under job quality of service (QoS) requirements. ***The proposed research program will make contributions to 5G wireless networks, SDN and cloud computing centers, which will contribute to the realization of IoT. The proposed research will benefit the telecommunications industry in Canada which is a strategic economic sector.**

下一代互联网，通常被称为物联网（IoT），有可能显着改善我们的日常生活。物联网将允许通过基于移动的机器对机器（M2M）通信实现异构智能对象的全球互连。智能对象的列表包括智能手机，智能汽车，家庭和城市，物联网预计将在交通，医疗保健，智能环境（家庭，办公室，工厂）和社交网络中找到应用。物联网在要连接的设备数量、通信、鲁棒性、安全性和大数据方面提出了许多新的挑战。预计物联网中部署的设备数量将达到数万亿。大多数要连接的移动的设备的处理能力、存储和电池寿命都有限。云计算将提供移动的设备所需的额外计算能力和存储。大量的原始数据将通过实时传感器不断收集，并存储在云中进行分析和推理，这将创造新的知识。* 无线通信预计将在物联网中发挥关键作用，因为它将为移动的用户提供接入，传感器网络等。对更高数据速率和大量具有不同服务质量（QoS）要求的无线设备连接到互联网的需求正在为下一代（5G）无线网络带来新的挑战。据设想，5G网络将通过非常密集的部署，进入毫米波长频谱和集中处理来满足这些需求。预计5G技术将产生分层异构网络架构（HetNet）。HetNet将具有多层小区架构，小区大小从宏小区到小小区不等。随着网络变得更密集，由于多小区干扰，干扰管理将变得更加关键。因此，已经提出了通过软件定义网络（SDN）管理来集中控制无线电接入网络以用于有效的资源分配和干扰管理。* 本研究提案的一个非常重要的目标是开发和优化5G网络的网络架构和通信协议。我们将考虑在5G网络中优化资源分配、能源效率和QoS配置，以最大限度地提高网络效用。我们将开发用于网络设计的优化工具以及用于在线实施的启发式算法。我们还将考虑在作业服务质量（QoS）要求下的云计算中心的资源分配优化。* 拟议的研究计划将为5G无线网络，SDN和云计算中心做出贡献，这将有助于实现物联网。拟议的研究将有利于加拿大的电信业，这是一个战略性的经济部门。
