Over the past two decades, the number and diversity of devices have increased significantly, particularly with the evolution of the Internet of Things, leading to the adoption of a wide range of wireless communication interfaces. This technological diversification has motivated the development of new theoretical models, commonly referred to as multi-interface wireless networks, which extend classical graph optimization problems by assuming that each device, represented as a vertex, is equipped with a set of available communication interfaces. In this work, we provide a concise overview of the most relevant research problems in the area of multi-interface wireless networks and survey the main coverage models together with their associated computational results.
