Center node: "internet of things an overview"
  Abstract: As technology proceeds and the number of smart devices continues to grow substantially, the need for ubiquitous context-aware platforms that support an interconnected, heterogeneous, and distributed network of devices has given rise to what is referred today as Internet of Things. However, paving the path for achieving the aforementioned objectives and making the IoT paradigm more tangible requires integration and convergence of different knowledge and research domains, covering aspects from identification and communication to resource discovery and service integration. Throughout this chapter, we aim to highlight research on topics that include proposed architectures, security and privacy, and network communication means and protocols; we eventually conclude by providing details of future directions and open challenges that face the IoT development.

  with members:
    - "privacy and data protection by design from policy to engineering"
    - "human data interaction the human face of the data driven society"
