With the proliferation of a number of IoT-based service providers in the market, it would be difficult to select a suitable IoT service as per the requirement among the vast pool of available services showing similar capabilities. Quality-of-service (QoS) parameters that define a service may be used for doing an appropriate selection. Here we consider IoT as the composition of its three possible components: Things, communication entity and computing entity, and description of an IoT may include QoS parameters for each of these components. We propose a framework that makes use of a multi-criteria decision making (MCDM) as a combination of known approaches under the names Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) for conducting the selection process where QoS parameters of various component of IoT act as criteria. We demonstrate the effectiveness of the proposed approach along with the sensitivity analysis for showing the robustness of the proposed framework.

随着市场上许多基于IoT的服务提供商的激增，很难根据显示相似功能的大量可用服务中的要求，选择合适的IoT服务。定义服务的服务质量（QoS）参数可用于进行适当的选择。在这里，我们将物联网视为其三个可能组件的组成：事物，通信实体和计算实体，物联网的描述可能包括这些组件中每个组件的QoS参数。我们提出了一个框架，该框架利用多标准决策（MCDM）作为已知方法的组合，以名称为“层次分析法（AHP）”和“通过与理想解决方案相似的优先顺序的技术（TOPSIS）”来进行选择过程IoT各个组成部分的QoS参数充当标准。我们展示了所提出的方法的有效性以及敏感性分析，以显示所提出框架的鲁棒性。
