In the last few years, classical social networking is turning into the more complex social internetworking and is extending from human users to objects. Indeed, objects are becoming increasingly complex, smart and social so that several authors have recently started to investigate the Social Internet of Things (SIoT) and the Multiple IoT (MIoT) paradigms. SIoT is more oriented to the technological issues to be faced in presence of multiple IoT interacting with each other. Instead, MIoT addresses data-driven and semantics-based aspects because it considers the contents exchanged by smart objects during their transactions. In such a research context, the concept of scope in a Multi-IoT scenario can play an important role. In this paper, we investigate this issue. In particular, first we define the concept of scope in a Multi-IoT scenario. Then, we propose two formalizations of this concept allowing the computation of its values. Afterwards, we present two possible applications of scope. Finally, we describe a set of experiments performed for its evaluation; the last of them compares scope with diffusion degree and influence degree, two parameters already proposed in past literature.

在过去的几年中，传统的社交网络正在转变为更复杂的社交网络，并从人类用户扩展到对象。实际上，对象正变得越来越复杂，智能和社交化，因此一些作者最近开始研究社交物联网（SIoT）和多物联网（MIoT）范例。SIoT更着重于在存在多个IoT交互时要面对的技术问题。相反，MIoT解决了数据驱动和基于语义的方面，因为它考虑了智能对象在事务处理期间交换的内容。在这样的研​​究背景下，范围的概念在多物联网场景中可以发挥重要作用。在本文中，我们将对此问题进行调查。特别是，首先，我们在Multi-IoT场景中定义范围的概念。然后，我们提出了此概念的两种形式化形式，可以计算其值。之后，我们介绍范围的两种可能的应用。最后，我们描述了一组用于评估的实验；最后，他们将范围与扩散程度和影响程度进行了比较，这是过去文献中已经提出的两个参数。
