The significant improvement in the field of Internet of Things (IoT) has made human life more sophisticated. In fact, the IoT is covering devices and appliances that support one or more common ecosystems, and can be controlled via devices associated with that ecosystem. This control is only possible by building an architecture. Whether in indoor or outdoor environments, IoT services are only available to individuals or pedestrians because a IoT architecture enables that the quality of its components (i.e. Cloud/Fog servers, protocol communication and IoT devices) and the way they interact are directly correlated in terms of effectiveness and applicability. This paper aims to provide a comprehensive overview of an architecture in pedestrian-oriented applications in an IoT environment. Moreover, our survey has taken into account the main challenges and limitations of each component of IoT technology
