The Internet of Things (IoT) is expected to connect billions of objects and devices through a dynamic global information exchange leading to diverse applications that will impact every aspect of our society. Sensing and data collection tasks in IoT systems are usually performed by wireless sensor networks (WSN) which represent a fundamental part of any IoT system. However, heterogeneous sensor technologies, dynamic user behaviour, and limited resources in terms of energy, bandwidth, and computing make IoT system design and deployment very challenging. To address these issues, this research program proposes effective resource management algorithms and tools in WSN for IoT systems. In particular, we propose joint optimization of energy, spectrum, and computing resources based on context information and user experience. Our approach is based on distributed learning and adaptation across the WSN, where nodes exchange information about the available and predicted resources, environment conditions, and user behaviour. Local and global optimization algorithms are then employed to optimize resource allocation at the node, cluster, and network levels. New dynamic hierarchical clustering techniques as well as Sensing-as-a-Service strategies will be investigated. Moreover, virtual clustering will be investigated in heterogeneous IoT networks to bridge data silos between the different IoT verticals. Here we propose joint optimization of data computing resources across WSN nodes, network edge (Fog nodes), and the Cloud.

物联网 (IoT) 预计将通过动态的全球信息交换连接数十亿个物体和设备，从而产生影响我们社会各个方面的多样化应用。物联网系统中的传感和数据收集任务通常由无线传感器网络 (WSN) 执行，无线传感器网络是任何物联网系统的基本组成部分。然而，异构传感器技术、动态用户行为以及能源、带宽和计算方面的有限资源使得物联网系统的设计和部署非常具有挑战性。为了解决这些问题，本研究项目提出了物联网系统无线传感器网络中有效的资源管理算法和工具。特别是，我们提出基于上下文信息和用户体验的能源、频谱和计算资源的联合优化。我们的方法基于整个 WSN 的分布式学习和适应，其中节点交换有关可用和预测资源、环境条件和用户行为的信息。然后采用局部和全局优化算法来优化节点、集群和网络级别的资源分配。将研究新的动态层次聚类技术以及传感即服务策略。此外，将在异构物联网网络中研究虚拟集群，以桥接不同物联网垂直领域之间的数据孤岛。在这里，我们提出跨 WSN 节点、网络边缘（雾节点）和云的数据计算资源的联合优化。
